    The nuclear spin–lattice relaxation time (T1) of lanthanum and aluminum nuclei in a single crystal of lanthanum aluminate doped with neodymium ions is studied to estimate the feasibility of the dynamically polarized lanthanum target applicable to beam experiments. The application of our interest is the study of fundamental discrete symmetries in the spin optics of epithermal neutrons. This study requires a highly flexible choice of the applied magnetic field for neutron spin control and favors longer T1 under lower magnetic field and at higher temperature. The T1 of 139La and 27Al was measured under magnetic fields of 0.5–2.5 T and at temperatures of 0.1–1.5 K and found widely distributed up to 100 h. The result suggests that the T1 can be as long as T1∼ 1 h at 0.1 K with a magnetic field of 0.1 T, which partially fulfills the requirement of the neutron beam experiment. Possible improvements to achieve a longer T1 are discussed.

    Structure factors describe how incident radiation is scattered from materials such as silicon and germanium and characterize the physical interaction between the material and scattered particles. We used neutron Pendellösung interferometry to make precision measurements of the (220) and (400) neutron-silicon structure factors and achieved a factor-of-four improvement in the (111) structure factor uncertainty. These data provide measurements of the silicon Debye-Waller factor at room temperature and the mean square neutron charge radius 〈rn2 〉 ¼ -0:1101T0:0089 square femtometers. Combined with existing measurements of the Debye-Waller factor and charge radius, the measured structure factors also improve constraints on the strength of a Yukawa modification to gravity by an order of magnitude over the 20 picometer–to–10 nanometer length scale range.

    The violation of baryon number, is an essential ingredient for the preferential creation of matter over antimatter needed to account for the observed baryon asymmetry in the Universe. However, such a process has yet to be experimentally observed. The HIBEAM/NNBAR program is a proposed two-stage experiment at the European Spallation Source to search for baryon number violation. The program will include high-sensitivity searches for processes that violate baryon number by one or two units: free neutron-antineutron oscillation via mixing, neutron-antineutron oscillation via regeneration from a sterile neutron state , and neutron disappearance (n → n′); the effective process of neutron regeneration is also possible. The program can be used to discover and characterize mixing in the neutron, antineutron and sterile neutron sectors. The experiment addresses topical open questions such as the origins of baryogenesis and the nature of dark matter, and is sensitive to scales of new physics substantially in excess of those available at colliders. A goal of the program is to open a discovery window to neutron conversion probabilities (sensitivities) by up to three orders of magnitude compared with previous searches. The opportunity to make such a leap in sensitivity tests should not be squandered. The experiment pulls together a diverse international team of physicists from the particle (collider and low energy) and nuclear physics communities, while also including specialists in neutronics and magnetics.

    Neutron energy-dependent angular distributions were observed for individual γ rays from the 0.74 eV p-wave resonance of La139+n to several lower excited states of La140. The γ-ray signals were analyzed in a two-dimensional histogram of the γ-ray energy, measured with distributed germanium detectors, and neutron energy, determined with the time-of-flight of pulsed neutrons, to identify the neutron energy dependence of the angular distribution for each individual γ rays. The angular distribution was also found for a photopeak accompanied with a faint p-wave resonance component. Our results can be interpreted as interference between s- and p-wave amplitudes, which may be used to study discrete symmetries of fundamental interactions.

    A neutron lifetime measurement conducted at the Japan Proton Accelerator Research Complex (J-PARC) is counting the number of electrons from neutron decays with a time projection chamber (TPC). The γ rays produced in the TPC cause irreducible background events. To achieve the precise measurement, the inner walls of the TPC consist of 6Li-enriched lithium-fluoride (6LiF) tiles to suppress the amount of γ rays. In order to estimate the amount of γ rays from the 6LiF tile, prompt gamma ray analysis (PGA) measurements were performed using germanium detectors. We reconstructed the measured γ-ray energy spectrum using a Monte Carlo simulation with the stripping method. Comparing the measured spectrum with a simulated one, the number of γ rays emitted from the6LiF tile was (2.3+0.7-0.3) × 10-4 per incident neutron. This is 1.4+0.5-0.2 times the value assumed for a mole fraction of the 6LiF tile. We concluded that the amount of γ rays produced from the 6LiF tile is not more twice the originally assumed value.

    A neutron detector using a fine-grained nuclear emulsion has a sub-micron spatial resolution and thus has potential to be applied as high-resolution neutron imaging. In this paper, we present two approaches to applying the emulsion detectors for neutron imaging. One is using a track analysis to derive the reaction points for high resolution. From an image obtained with a 9 µm pitch Gd grating with cold neutrons, periodic peak with a standard deviation of 1.3 µm was observed. The other is an approach without a track analysis for high-density irradiation. An internal structure of a crystal oscillator chip, with a scale of approximately 30 µm, was able to be observed after an image analysis.

    The neutron lifetime has been measured by comparing the decay rate with the reaction rate of 3He nuclei of a pulsed neutron beam from the spallation neutron source at the Japan Proton Accelerator Research Complex (J-PARC). The decay rate and the reaction rate were determined by simultaneously detecting electrons from the neutron decay and protons from the 3He(n,p)3H reaction using a gas chamber, the working gas of which contains diluted 3He. The measured neutron lifetime was 898 ± 10stat+15-18 sys s.

    We have submitted a secular variation (SV) candidate model for the thirteenth generation of International Geomagnetic Reference Field model (IGRF-13) using a data assimilation scheme and a magnetohydrodynamic (MHD) dynamo simulation code. This is the first contribution to the IGRF community from research groups in Japan. A geomagnetic field model derived from magnetic observatory hourly means, and CHAMP and Swarm-A satellite data, has been used as input data to the assimilation scheme. We adopt an ensemble-based assimilation scheme, called four-dimensional ensemble-based variational method (4DEnVar), which linearizes outputs of MHD dynamo simulation with respect to the deviation from a dynamo state vector at an initial condition. The data vector for the assimilation consists of the poloidal scalar potential of the geomagnetic field at the core surface and flow velocity field slightly below the core surface. Dimensionless time of numerical geodynamo is adjusted to the actual time by comparison of secular variation time scales. For SV prediction, we first generate an ensemble of dynamo simulation results from a free dynamo run. We then assimilate the ensemble to the data with a 10-year assimilation window through iterations, and finally forecast future SV by the weighted sum of the future extension parts of the ensemble members. Hindcast of the method for the assimilation window from 2004.50 to 2014.25 confirms that the linear approximation holds for 10-year assimilation window with our iterative ensemble renewal method. We demonstrate that the forecast performance of our data assimilation and forecast scheme is comparable with that of IGRF-12 by comparing data misfits 4.5 years after the release epoch. For estimation of our IGRF-13SV candidate model, we set assimilation window from 2009.50 to 2019.50. We generate our final SV candidate model by linear fitting for the weighted sum of the ensemble MHD dynamo simulation members from 2019.50 to 2025.00. We derive errors of our SV candidate model by one standard deviation of SV histograms based on all the ensemble members.[Figure not available: see fulltext.].

    We are developing a neutron polarizer with polarized 3He gas, referred to as a 3He spin filter, based on the Spin Exchange Optical Pumping (SEOP) for polarized neutron scattering experiments at Materials and Life Science Experimental Facility (MLF) of Japan Proton Accelerator Research Complex (J-PARC). A 3He gas-filling station was constructed at J-PARC, and several 3He cells with long spin relaxation times have been fabricated using the gas-filling station. A laboratory has been prepared in the MLF beam hall for polarizing 3He cells, and compact pumping systems with laser powers of 30 W and 110 W, which can be installed onto a neutron beamline, have been developed. A 3He polarization of 85% was achieved at a neutron beamline by using the pumping system with the 110 W laser. Recently, the first user experiment utilizing the 3He spin filter was conducted, and there have been several more since then. The development and utilization of 3He spin filters at MLF of J-PARC are reported.

    The attenuation of seismic wave energy is caused by intrinsic absorption and scattering. The former involves the conversion of seismic wave energy to heat energy via internal friction due to the anelasticity of the medium, whereas the latter involves the scattering of seismic wave energy due to random elastic heterogeneities in the medium. Quantifying both intrinsic ((Formula presented.)) and scattering ((Formula presented.)) attenuation is therefore important for understanding the physical properties of the Earth's interior and predicting seismic wave propagation. Here we develop a new procedure to separately map three-dimensional (3-D) (Formula presented.) and (Formula presented.) structures. The path-averaged (Formula presented.) and (Formula presented.) values are obtained via an envelope-fitting approach that employs a multiple-scattering model. The path-averaged (Formula presented.) and (Formula presented.) structures are then mapped into 3-D space using a tomographic inversion technique based on sensitivity kernels, which are calculated from a Monte Carlo simulation of the radiative transfer equations. We apply this method to map the crustal structure beneath Kyushu, Japan, and obtain 3-D (Formula presented.) and (Formula presented.) structures for the 1–2, 2–4, and 4–8 Hz frequency bands. The spatial attenuation patterns are similar for each of the analyzed frequency bands, with the spatial variability in (Formula presented.) being more pronounced than that in (Formula presented.). The high- (Formula presented.) and (Formula presented.) regions correspond to the locations of active volcanoes. Conversely, the northern Kyushu area possesses low- (Formula presented.) and (Formula presented.) zones that correspond to low heat flow and Cretaceous granite, respectively. The overall (Formula presented.) and (Formula presented.) distributions correlate with thermal and geological structures, respectively.

    An sp-mixing model, which describes a compound nuclear reaction by mixing partial waves, predicts a correlation term in this reaction. A detailed study of the sp-mixing model is required to study the feasibility of a new type of time reversal symmetry violation search experiment. The correlation term σn·(kn×kγ) in the La139(n - ,γ) reaction has been studied by measuring γ-ray and neutron energies utilizing epithermal polarized neutrons and germanium detectors. The transverse asymmetry for single γ-ray transition was measured to be 0.60±0.19 in the p-wave resonance.

    For the purpose of future visualization of the flow field in superfluid helium-4, clusters of the triplet state excimer 4He2* are generated along the micro-scale recoil tracks of the neutron-absorption reaction n + 3He → 3T + p. This reaction is induced by neutron irradiation of the 3He fraction contained in natural isotopic abundance liquid helium with neutron beams either from the Japan Proton Accelerator Research Complex, Materials and Life Science Experimental Facility (JPARC)/Materials and Life Science Experimental Facility or from the Kyoto University Institute for Integrated Radiation and Nuclear Science. These 4He2* clusters are expected to be ideal tracers of the normal-fluid component in superfluid helium with several advantageous properties. Evidence of the excimer generation is inferred by detection of laser induced fluorescence emitted from the 4He2* clusters excited by a purpose-built short pulse gain-switched titanium:sapphire (Ti:sa) laser operating at a wavelength of 905 nm. The setup and performance characteristics of the laser system including the Ti:sa and two continuous wave re-pumping lasers are described. Detection at the fluorescence wavelength of 640 nm is performed by using optical bandpass filtered photomultiplier tubes (PMT). Electrical noise in the PMT acquisition traces could successfully be suppressed by post-processing with a simple algorithm. Despite other laser-related backgrounds, the excimer was clearly identified by its fluorescence decay characteristics. Production of the excimer was found to be proportional to the neutron flux, adjusted via insertion of different collimators into the neutron beam. These observations suggest that the apparatus we constructed does function in the expected manner and, therefore, has the potential for groundbreaking turbulence research with superfluid helium.

    Precision measurements of slow neutron cross sections with atoms have several scientific applications. In particular, the n-He4 s-wave scattering length is important to know both for helping to constrain the nuclear three-body interaction and for the proper interpretation of several ongoing slow neutron experiments searching for other types of neutron-atom interactions. We present new measurements of the ratios of the neutron differential scattering cross sections of the noble gases He, Ar, Kr, and Xe to Ne. All gases used were of natural isotopic abundance. These measurements were performed using a recently developed neutron-scattering apparatus for gas samples located on a pulsed slow neutron beamline which was designed to search for possible exotic neutron-atom interactions and employs both neutron time of flight information and a position-sensitive neutron detector for scattering event reconstruction. We found agreement with the literature values of scattering cross sections inferred from Ar/Ne, Kr/Ne, and Xe/Ne differential cross-section ratios over the q range of 1-7 nm-1. However, for the case of He/Ne we find that the cross section inferred differs by 11.3% (7.6σ) from previously reported values inferred from neutron phase-shift measurements, but is in reasonable agreement with values from other measurements. The very large discrepancy in the He/Ne ratio calls for a new precision measurement of the n-He4 scattering length using neutron interferometry.

    <p>Accelerator technique for neutrons is discussed in this article. In the case of pulsed neutrons, the velocity is well-defined as a function of their arrival time. Electromagnetic neutron accelerator/decelerator synchronized with the neutron time-of-flight is capable of selectively changing the neutron velocity and concentrating the velocity distribution. Possible enhancement of the neutron intensity at a specific neutron velocity is calculated by using numerical simulations. This technique, for example, can be applied to efficient conversion of ultra-cold neutrons with superfluid helium.</p>

    In a neutron lifetime measurement at the Japan Proton Accelerator Complex, the neutron lifetime is calculated from the neutron decay rate and the incident neutron flux. The flux is obtained by counting the protons emitted from the neutron absorption reaction of 3He gas, which is diluted in a mixture of working gas in a detector. Hence, it is crucial to determine the amount of 3He in the mixture. In order to improve the accuracy of the number density of the 3He nuclei, we have suggested using the 14N(n, p)14C reaction as a reference because this reaction involves similar kinetic energy to the 3He(n,p)3 H reaction and a smaller reaction cross section to introduce reasonable large partial pressure. The uncertainty of the recommended value of the cross section, however, is not satisfied with our requirement. In this paper we report the most accurate experimental value of the cross section of the 14N(n,p)14C reaction at a neutron velocity of 2200 m s-1, measured relative to the 3He(n,p)3H reaction. The result was 1.868 \pm 0.003 (stat.) ± 0.006 (sys.) b. Additionally, the cross section of the 17O(n,α)14C reaction at the neutron velocity is also redetermined as 249 ± 6 mb.

    Large sources of parity violation have been observed in compound nuclear reactions. These enhancements are described by the compound nuclear model, which can be used to describe the angular correlation of γ-rays produced in (n; γ) reactions in medium-heavy nuclei. It has also been suggested that these same reactions could lead to a similar enhancement in time reversal violating processes. Therefore, we are interested in verifying the compound nuclear model by studying the (n; γ) reaction using polarized neutrons. In this paper, we discuss the installation and characterization of a neutron polarizer used in the (n; γ) measurement with transversely polarized neutrons.

    The Nd3+ doped LaAlO3 crystal is a good candidate of a polarized 139La target for the search of the P-odd and T-odd interaction in the low-energy neutron absorption of 139La. As the first step for realizing the polarized 139La target, we grow the undoped LaAlO3 crystal and the La1−xNdxAlO3 (x = 5 ×10−4) crystal by floating-zone method with four halogen lamps. The ESR measurements of Nd3+ in the latter crystal indicated that the linewidth was about 6 gauss, whose value is the same as the crystal in which 50 % 139La polarization was achieved in the previous DNP experiment. As the result, the crystals grown by this method can be applicable to the target study for the T-violation search.

    The fundamental parity violation is enhanced by 106 times at maximum in several neutron induced compound nuclei. There is a theoretical prediction that fundamental T-violating effects can be also largely enhanced in compound nuclei implying that T-violation can be searched for by making very sensitive measurements. A T-violation search experiment using compound nuclei is planned at J-PARC. Polarized epithermal neutron beam, polarized nuclear target, and high count rate neutron detector are necessary for the experiment, and therefore a development of the neutron polarizer using polarized 3He is ongoing at J-PARC in JAEA. Recently, a clean vacuum system to fabricate 3He spin filters was constructed, and several 3He spin filters were fabricated. The current status of the development of the 3He spin filter was reported.

    © 2018 American Physical Society. We describe an experimental search for deviations from the inverse-square law of gravity at the nanometer length scale using neutron scattering from noble gases on a pulsed slow neutron beam line. By measuring the neutron momentum transfer (q) dependence of the differential cross section for xenon and helium and comparing to their well-known analytical forms, we place an upper bound on the strength of a new interaction as a function of interaction length λ which improves upon previous results in the region λ<0.1 nm, and remains competitive in the larger-λ region. A pseudoexperimental simulation is developed for this experiment and its role in the data analysis is described. We conclude with plans for improving sensitivity in the larger-λ region.

    The velocity of neutrons from a pulsed neutron source is well defined as a function of their arrival time. An electro-magnetic neutron accelerator/decelerator synchronized with the neutron time-of-flight is capable of selectively changing the neutron velocity and concentrating the velocity distribution. The possible enhancement of the neutron intensity at a specific neutron velocity by orders of magnitude is discussed, together with an experimental design.

    A pulsed cold neutron beam for the study of neutron optics and fundamental physics (NOP) is under construction as the BL05 of the spallation neutron source of the J-PARC. The NOP beamline has three beam branches, which provide the highly-polarized beam, high intensity beam and low divergence beam for the neutron decay experiment, the neutron scattering experiment and the neutron interferometry experiment, respectively. We overview the physics to be studied at the NOP beamline at its beginning stage.

    We have carried out detailed systematic studies of relaxation effects, which contribute to a significant improvement in proton polarization in a single crystal of naphthalene doped with pentacene. The experiments have been performed in a magnetic field of 3 kG at room temperature or at 77 K and with a pulsed dye laser or a pulsed N<SUB>2</SUB> laser. We have found that a relaxation rate in the presence of irradiation with visible light (λ=595 nm) is much smaller than that with ultraviolet light (λ=337 nm) at room temperature, although the absorption rate of visible light is much larger than that of ultraviolet light. By cooling the crystal, the slow motion of the naphthalene molecules, which is a dominant relaxation process, can be suppressed. Surprisingly, we have found that the relaxation time at 77 K in the presence of the dye laser becomes long, but still depends on the laser power. Our investigation has also indicated that both the longer relaxation time and the irradiation with the dye laser lead to a great improvement in the polarization of protons in the bulk of a crystal from 0.5% at room temperature to 32% at 77 K.

    © 2018 American Physical Society. The angular distribution of individual γ rays, emitted from a neutron-induced compound-nuclear state via radiative capture reaction of La139(n,γ) has been studied as a function of incident neutron energy in the epithermal region by using germanium detectors. An asymmetry ALH was defined as (NL-NH)/(NL+NH), where NL and NH are integrals of low- and high-energy region of a neutron resonance respectively, and we found that ALH has the angular dependence of (Acosθγ+B), where θγ is the emitted angle of γ rays, with A=-0.3881±0.0236 and B=-0.0747±0.0105 in 0.74 eV p-wave resonance. This angular distribution was analyzed within the framework of interference between s- and p-wave amplitudes in the entrance channel to the compound-nuclear state, and it is interpreted as the value of the partial p-wave neutron width corresponding to the total angular momentum of the incident neutron combined with the weak matrix element, in the context of the mechanism of enhanced parity-violating effects. Additionally, we use the result to quantify the possible enhancement of the breaking of time-reversal invariance in the vicinity of the p-wave resonance.

    © 2018 IOP Publishing Ltd and Sissa Medialab. In this study, the germanium detector assembly, installed at the Accurate Neutron-Nuclear Reaction measurement Instruments (ANNRI) in the Material and Life Science Facility (MLF) operated by the Japan Proton Accelerator Research Complex (J-PARC), has been characterized for extension to the measurement of the angular distribution of individual γ-ray transitions from neutron-induced compound states. We have developed a Monte Carlo simulation code using the GEANT4 toolkit, which can reproduce the pulse-height spectra of γ-rays from radioactive sources and (n,γ) reactions. The simulation is applicable to the measurement of γ-rays in the energy region of 0.5-11.0 MeV.

    We developed a neutron detector with submicron spatial resolution by incorporating Li-6 into a fine-grained nuclear emulsion. Upon exposure to thermal neutrons, tracks from neutron capture events were observed. The detector spatial resolution was estimated from their grain density. Detection efficiency was measured using the detector response to cold neutrons. (C) 2017 The Authors. Published by Elsevier B.V.

    We have developed a compact permanent-magnet sextupole lens for neutrons that can focus a pulsed beam with a wide wavelength range-the maximum wavelength being more than double the minimum-while sufficiently suppressing the effect of chromatic aberration. The bore diameter is o15 mm. Three units of a double-ring sextupole with a length of 66 mm are cascaded, resulting in a total length of 198 mm. The dynamic modulation range of the unit-averaged field gradient is 1.06 x 10(4)-5.86 x 10(4) Tm-2. Permanent magnets and newly developed torque-canceling elements make the device compact, its production costs low, and its operation simpler than that of other magnetic lenses. The efficacy of this lens was verified using very cold neutrons. The diameter of the focused beam spots over the wavelength range of 27-55 angstrom was the same as that of the source aperture (2 mm diameter) when the magnification of the optical arrangement was unity. The total beam flux over this wavelength range was enhanced by a factor of 43. The focusing distance from the source to the detector was 1.84 m. In addition, in a demonstration of neutron image magnification, the image of a sample mask magnified by a factor of 4.1 was observed when the magnification of the optical arrangement was 5.0.

    We are developing a high-resolution small angle neutron scattering instrument for very cold neutrons (VCN). Our concept includes a magnetic lens for focusing of the beam at the detector plane. The lens consists of one permanent-magnet sextupole array rotating outside another stationary sextupole array, to focus a pulsed white beam of neutrons. Thus the instrument operates in time of flight mode. The prototype magnetic lens has a bore of 15 mm diameter and length of 66 mm, producing a magnetic field gradient oscillating from 1.5 x 10(4) to 5.9 x 10(4) T/m(2), with frequency &lt;= 25 Hz. A torque-canceling magnet around the lens suppresses the torque of rotation from the outer array to 1/3.
    We have demonstrated the performance of the lens, over wavelength range from 30 to 48 angstrom, on the PF2-VCN beam line at the Institut Laue-Langevin, France. The focused beam image was the same size as the source, without chromatic aberration, with focal length of 1.14 m. We also studied the performance of this configuration for high-resolution SANS, in a compact geometry (just 5 m long). The measurable q range of this system was 0.009 angstrom(-1) &lt;= q &lt;= 0.3 angstrom(-1) or 0.004 angstrom(-1) &lt;= q &lt;= 0.08 angstrom(-1) for sample to detector distances of 100 and 465 mm, respectively. Here, we present the results of our lens characterization study along with the SANS results on a tri-block copolymer (F127 Pluronic) and on a stretched polymer blend (with the Shish-Kebab structure).

    For the future fundamental physics experiments by using cold neutrons, we are developing a device which can measure the neutron polarization degree by accuracy significantly below 10(-3). A quadrupole magnet is one of the promising candidate to measure the neutron polarization degree by such extremely high precision. We have performed a polarization experiment by using the quadrupole magnets at the Very Cold Neutron (VCN) port of the PF-2 in the Institute Laue-Langevin (ILL). As a result, we obtained the polarization degree P with very high accuracy P=0.9994 +/- 0.0001(stat.) +/- 0.0003(syst.), which meet our requirement significantly. (C) 2010 Elsevier B.V.

    Neutron reflectometry was applied for the characterization of machined roughness on iron surfaces, including a buried solid-solid contacting surface. The observed distribution of the reflected neutron beam could be explained using a structure factor estimated from the Fourier transform of the physical roughness measured by a contact-type roughness gauge, particularly in the case of a periodic surface structure. In the case of random roughness, the accumulation of beams specularly reflected from every small local region of the surface gave a better explanation of the broad distribution of the scattered beam, where each local region was assumed to be flat and differently inclined relative to the incident beam direction. When the surface was buried beneath another material, the width of the distribution of the reflected beam became slightly wider than that in air. Although neutron reflectometry for the characterization of surface roughness has various limitations, it is still an effective tool for nondestructively observing the surface roughness at a buried contacting surface.

    We obtained highly polarized very cold neutrons through a quadrupole magnet with a large aperture. When neutrons go through a quadrupole magnet, parallel-spin neutrons are attracted to the magnet axis and anti-parallel-spin neutrons are repelled off the axis. Therefore, the neutrons through a sufficiently long quadrupole magnet have completely parallel-spin. At the downstream of the quadrupole magnet, we placed another quadrupole magnet to divide neutrons into two regions depending on their spin directions. We obtained the neutron polarization from the integrated count of the two regions and found it was 99.88±0.09 (stat.)±0.05 (syst.)%. © 2009 Elsevier B.V. All rights reserved.

    Modulating permanent magnet sextupole lens (PMSx) for focusing pulsed cold neutrons is under development. The synchronized modulation of its field gradient suppresses the chromatic aberration which arises from the Time Of Flight method. The strength of the magnetic field, the torque, and the rise of temperature during its operation are studied on a fabricated prototype. Experiments on focusing pulsed very cold neutrons (VCN) at ILL (Institute of Laue Langevin, France) were carried out and VCN with around λ=40 Å were focused by the PMSx at a focal length of about 0.5 m. The experimental results are presented in conjunction with the principle of the neutron focusing and the modulating method of the focal strength of permanent magnet lens with the double ring structure. © 2009 Elsevier B.V.

    As a magnetic neutron lens based on a sextupole magnet to focus neutrons has chromatic aberration, it has been proposed that the chromatic aberration can be compensated in the pulsed neutron beam focusing by combining the focusing and defocusing functions of the multiplet magnetic lens system synchronously with time-of-flight (TOF) of neutrons. In this study, we performed numerical simulations on the multiplet magnetic lens system to investigate how a pulsed neutron beam can be controlled on the basis of the TOF method. It was then confirmed that the chromatic aberration can be compensated and the focal condition can be maintained over a certain A-range by utilizing plural magnetic lenses in series and choosing the focusing and defocusing function of each magnetic lens synchronously with TOF of neutrons.

    We have developed a pixel detector for ultra-cold neutrons using a commercial CCD. In order to detect neutrons, a thin neutron converting layer is directly formed on the CCD surface. The detection efficiencies for cold, very-cold and ultra-cold neutrons are measured to be 1.7%, 4.05 +/- 0.08 +/- 0.12% and 40.6 +/- 0.7 +/- 2.8%, respectively. The spatial resolutions were measured to be 2.9 +/- 0.1 mu m for horizontal direction and 4.4 +/- 0.2 mu m for vertical direction. The vertical and horizontal directions are determined by the charge transfer mechanism of CCDs. The details of the pixel detector and its performance tests are described.

    We performed a cold neutron polarization experiment using a polarization device based on a quadrupole magnet. By passing through the aperture of the quadrupole magnet, positive and negative polarity neutrons are accelerated in opposite directions and spatially separated due to the magnetic field gradient. Then, we extracted the one-spin component and analyzed the polarization degree by using a sextupole magnet and position-sensitive detector. As a result, very high neutron polarization degree P = 0.9993 +/- 0.0025 was obtained. Advantages of the quadrupole magnet as the neutron polarization device and its application to neutron scattering experiments are discussed. (c) 2007 Elsevier B.V. All rights reserved.

    Precise measurement of neutron beta decay tests predictions of the Standard Model of electroweak interaction. The coefficient a of the antineutrino/electron angular correlation is determined by measuring the energy spectrum of the recoil protons generated in the neutron beta decay. A proton spectrometer required for this measurement demands high detection efficiency, high energy resolution and a large detection area. We have begun development of a Transition Edge Sensor (TES) microcalorimeter for use as a low energy particle detector. To realize the large detection area we have designed a pixelated TES array incorporating a parallel biasing scheme. Our TES device consists of 4-pixels using a Au/Ti/Au trilayer film adjusted to a superconducting transition temperature of Tc similar to 380 mK. This temperature is convenient for use in a 3He cryostat with a pulse tube refrigerator. The Ail films improve thermal conductivity, thereby reducing position dependent effects and allow an increased detector area.

    In order to extend an upper q-limit [q is the magnitude of the scattering vector q, defined by q = (4 pi/lambda)sin theta, where lambda and 2 theta are the wavelength and the scattering angle, respectively], high-angle He-3 sub-detectors were installed on a focusing and polarized neutron small-angle scattering spectrometer (SANS-J-II) at JRR-3, Tokai, Japan. Consequently, the upper q-limit was improved from 0.2 to 2.0 angstrom(-1). To quantitatively discriminate spin incoherent scattering from hydrogen or to perform nuclear spin polarization contrast variation, a remanent supermirror analyser is also available on the high-angle sub-detector. By combining a focusing ultra-small-angle scattering, realised by compound and/or magnetic lens and high-resolution area detector, SANS-J-II is able to cover from 3 x 10(-4) to 2.0 angstrom(-1) (four orders of magnitude of q), which benefits investigation of hierarchically ordered systems, found widely in hard, soft and bio-materials.

    SANS-J (a pinhole small-angle neutron scattering spectrometer at research reactor JRR3, Tokai, Japan) was reconstructed as a focusing and polarized neutron small-angle scattering spectrometer (SANS-J-II). By employing focusing lenses of a biconcave MgF2 crystal or of a sextupole permanent magnet and a high-resolution photomultiplier, the minimum accessible magnitude of the scattering vector q(min) was improved from 3 x 10(-3) angstrom(-1) to an ultra-small-angle scattering (USAS) of 3 x 10(-4) angstrom(-1). Compared with a Bonse-Hart double-crystal method, the advantages of focusing USAS are the efficient detection of anisotropic USAS with an area detector, an improvement in q resolution Delta q/q at conventional magnitudes of the scattering vector q similar to 10(-3) angstrom(-1) and a gain in neutron flux in the conventional q region of q similar to 10(-3) angstrom(-1).

In this study, we investigated the performance of the FSANS instrument with the magnetic neutron lens. The intensity distribution of a direct neutron beam focused on the detector plane by the magnetic neutron lens had a ratio of the peak height to the background level of similar to 6 x 10(4) for a polarized neutron beam with a polarization degree of similar to 0: 99. It is found that a minimum value of the measurable q range [where q is the modulus of the scattering vector and is defined as q = (4 pi / lambda) sin(theta /2), where theta is the scattering angle and lambda is the neutron wavelength], q(min), of 6.5 x 10(-4) angstrom(-1) can be achieved by the FSANS instrument with the magnetic neutron lens using neutrons with lambda = 6.6 angstrom and Delta lambda/lambda = 0.13 for the full width at half maximum.

    We have proposed a Cryostat-integrated Superconducting Tunneling Junction (STJ), Single Flux Quantum Analog to Digital (SFQ-A/D) converter. The sampling frequency of the A/D converter was measured to be 12.7GHz with an SNR of 23.7dB. The integration of the STJ and the A/D converter makes possible the development of a multi-channel detector system that can be used in the detection of X-rays and THz electromagnetic waves with higher efficiency. The detection of the STJ is accompanied with the formation of magnetic field in the Cryostat. This magnetic field is a major drawback to the proper functioning of the SFQ. We have implemented magnetic shielding in the Cryostat which has resulted into the normal functioning of the SFQ-A/D converter.

    Terahertz radiation is the electromagnetic range between radio waves and light waves. The imaging technology in this range is expected to generate many novel applications such as nondestructive inspection in commercial industries and security systems, medical diagnosis and astronomy. However, detector arrays for terahertz imaging are still under development, and large-scale and high-sensitivity detector arrays are acutely needed in many fields. We have designed, fabricated, and characterized a superconducting detector array using superconducting tunnel junctions (STJs) for terahertz imaging applications. The detector is composed of linearly distributed junctions placed on a superconducting microstrip line and is integrated on two wings of a log-periodic antenna. It is based on the photon-assisted tunneling process. In this paper, we explain the detector outline, performances and future prospects, and demonstrate terahertz imaging using the STJ linear array.

    Neutron refractive optics is a powerful tool for beam focusing due to its large effective aperture compared to reflective optics. Because neutron refraction angle decreases with shorter wavelengths, the application of refractive optics has been restricted to the cold neutron range. To expand the applicable wavelength range, we have developed a new refractive optics using an amorphous perfluoropolymer. This refractive optics is composed of several hundred thin sheets, each of which has a large number of grooves on the top surface. The refraction experiment was performed at the H-8 beam port of KENS, and it was confirmed that the thermal neutron beam can be refracted using this material prism. (c) 2006 Elsevier B.V.

    Precise measurement of neutron beta decay allows determining the coupling constant of weak interaction independent of any nuclear structure. We have developed measurement system of neutron beta decay at a thermal neutron beamline in JRR-3, JAEA. By using coincidence technique of two kinds of detectors, we have succeeded in detecting the signal of neutron beta decay with S/N of 0.63 aud count rate of 0.40cps. (c) 2006 Elsevier B.V.

    We have developed a magnetic neutron lens (MNL) based on an extended Halbach-type permanent sextupole magnet. The effective aperture size is 30 mm in diameter and the length is 2400 mm. The sextupole magnetic field distribution vertical bar B vertical bar = (G/2) r(2) with the gradient coefficient G = 10,660 +/- 530 T/m(2) are generated inside the magnet, where r is the distance from the magnet center axis. The neutron-focusing property is investigated by using pulsed polarized neutrons. The obtained results are discussed in comparison with numerical simulation results. The application to the focusing-geometry small-angle neutron scattering experiments is discussed. (c) 2006 Elsevier B.V. All rights reserved.

    Moire fringes were observed as a bright and high-contrast image using a. neutron spin interferometer with a relatively divergent cold neutron beam at the MINE2 beam line of JRR-3M. The two spin states were selectively deflected with the relative angle in the range of 92-184 nrad on transmission through the magnetic field gradient in the range of 3.2-6.4 G/cm produced by a 5 cm long quadrupole electromagnet. We analyzed the result with a first-order calculation taking into account the finite beam divergence and found that the beam divergence is required to be less than the angular separation of individual Moire loci, for the observation of Moire fringes, and is not required to be less than the angular separation of the two beam paths.

    By employing focusing lenses of sextupole permanent magnet and biconcave MgF2 crystal, and high-resolution photomultiplier, SANS-J (pinhole small-angle neutron scattering spectrometer at research reactor JRR3, Tokai) was reconstructed to focusing and polarized neutron ultra-small-angle scattering spectrometer (SANS-J-II). Consequently, an accessible minimum wave number q(min) was improved from 3 x 10(-3) angstrom(-1) to 3 x 10(-4) angstrom(-1). Furthermore, we added He-3 sub-detectors with an analyzer super mirror at a sample position. With this setup, we perform polarization analysis at high q (&gt; U angstrom(-1)) in order to quantitatively discriminate spin incoherent scattering from hydrogen or to perform spin contrast variation, by a dynamic nuclear polarization method (&gt; 0.2 angstrom(-1)) (c) 2006 Elsevier B.V.

    We have developed a multichannel parabolic guide for thermal neutron beam focusing. The guide was designed with multichannel structure, seven channels in the present case, to focus a neutron beam with wide cross section effectively. The multichannel structure is made with parabolically bent NiC/Ti supermirrors with critical reflection angles in = 3.0 and 3.6 times as much as that of nickel and thickness of 0.55 mm. The guide consists of two focusing devices with each length of 900 mm, which are separated by a gap of 150 mm for neutron beta decay experiments. The focal length of the guide is 995 mm away from the exit of the guide. The cross section of the guide is 90 x 20 mm(2) at the entrance and 52.3 x 12.1 mm(2) at the exit. The guide was installed at a thermal neutron beam line for neutron-induced prompt gamma-ray analysis (PGA) of JRR-3M in JAEA with straight supermirror guides with in = 3.0. Focusing properties of the parabolic guide were measured at the focal point with a CCD imaging system and we obtained a gain of 9.6 and 4.1 in peak flux compared with those in cases of using the vacuum tube and the straight guide, respectively. The parabolic guide has been successfully used to enhance the efficacy of PGA and have also applied to neutron beta decay experiments. (c) 2006 Elsevier B.V. All rights reserved.

    We designed, fabricated; and characterized a superconducting detector array for terahertz imaging applications. To evaluate the optical performance as an imaging array, we measured the spectral response of a 5-pixel linear array detector, and confirmed its sensitivity peaks to be at the same frequency within accuracy of one percent in the range of 0.65 THz. The frequency peaks are also in good agreement with a numerical calculation. This linear array was tested in the nondestructive imaging of a metallic pattern and an integrated-circuit card, and allowed the shortening of the total acquisition time. High fabrication yield of about 99% was achieved for single superconducting tunnel junctions, which led to 90% yield for the detectors.

    Diagnosis using terahertz (THz) waves holds a great potential for various applications in fields such as medicine, biology, industry and agriculture because of its transmittance to soft matters as well as the good spatial resolution. In addition, the specific spectral absorption features can be also applicable for identifying materials inside opaque packages. In many such applications, imaging measurements with high sensitivity are required to obtain precisely the distribution of the transmitted THz waves of the measured objects and to distinguish the location of the materials of interest. We are developing two types of THz detectors using Nb-based superconducting tunnel junctions. In this paper, we introduce their detection principles, performances, and recent results including THz imaging.

    We are developing a broadband THz detectors using Nb-based superconducting tunnel junctions. We found two components in a current signal for 1-2 THz pulse input. From the comparison of results obtained for the signals, the frequency response for the different size of STJs and the STJs fabricated on different substrate materials, we demonstrate that they correspond to photons absorbed with the superconductor electrode ( referred as 'direct' component) and phonons generated by photons absorbed with the substrate ( referred as 'phononmediated' component).

    © 2018 American Physical Society. The angular distribution of individual γ rays, emitted from a neutron-induced compound-nuclear state via radiative capture reaction of La139(n,γ) has been studied as a function of incident neutron energy in the epithermal region by using germanium detectors. An asymmetry ALH was defined as (NL-NH)/(NL+NH), where NL and NH are integrals of low- and high-energy region of a neutron resonance respectively, and we found that ALH has the angular dependence of (Acosθγ+B), where θγ is the emitted angle of γ rays, with A=-0.3881±0.0236 and B=-0.0747±0.0105 in 0.74 eV p-wave resonance. This angular distribution was analyzed within the framework of interference between s- and p-wave amplitudes in the entrance channel to the compound-nuclear state, and it is interpreted as the value of the partial p-wave neutron width corresponding to the total angular momentum of the incident neutron combined with the weak matrix element, in the context of the mechanism of enhanced parity-violating effects. Additionally, we use the result to quantify the possible enhancement of the breaking of time-reversal invariance in the vicinity of the p-wave resonance.

    © 2018 American Physical Society. We describe an experimental search for deviations from the inverse-square law of gravity at the nanometer length scale using neutron scattering from noble gases on a pulsed slow neutron beam line. By measuring the neutron momentum transfer (q) dependence of the differential cross section for xenon and helium and comparing to their well-known analytical forms, we place an upper bound on the strength of a new interaction as a function of interaction length λ which improves upon previous results in the region λ<0.1 nm, and remains competitive in the larger-λ region. A pseudoexperimental simulation is developed for this experiment and its role in the data analysis is described. We conclude with plans for improving sensitivity in the larger-λ region.

    We summarize the state of the art of a program of UV observations from space of meteor phenomena, a secondary objective of the JEM-EUSO international collaboration. Our preliminary analysis indicates that JEM-EUSO, taking advantage of its large FOV and good sensitivity, should be able to detect meteors down to absolute magnitude close to 7. This means that JEM-EUSO should be able to record a statistically significant flux of meteors, including both sporadic ones, and events produced by different meteor streams. Being unaffected by adverse weather conditions, JEM-EUSO can also be a very important facility for the detection of bright meteors and fireballs, as these events can be detected even in conditions of very high sky background. In the case of bright events, moreover, exhibiting some persistence of the meteor train, preliminary simulations show that it should be possible to exploit the motion of the ISS itself and derive at least a rough 3D reconstruction of the meteor trajectory. Moreover, the observing strategy developed to detect meteors may also be applied to the detection of nuclearites, exotic particles whose existence has been suggested by some theoretical investigations. Nuclearites are expected to move at higher velocities than meteoroids, and to exhibit a wider range of possible trajectories, including particles moving upward after crossing the Earth. Some pilot studies, including the approved Mini-EUSO mission, a precursor of JEM-EUSO, are currently operational or in preparation. We are doing simulations to assess the performance of Mini-EUSO for meteor studies, while a few meteor events have been already detected using the ground-based facility EUSO-TA.

    JEM-EUSO is a space mission designed to investigate Ultra-High Energy Cosmic Rays and Neutrinos (E &gt; 5.10(19) eV) from the International Space Station (ISS). Looking down from above its wide angle telescope is able to observe their air showers and collect such data from a very wide area. Highly specific trigger algorithms are needed to drastically reduce the data load in the presence of both atmospheric and human activity related background light, yet retain the rare cosmic ray events recorded in the telescope. We report the performance in offline testing of the first level trigger algorithm on data from JEM-EUSO prototypes and laboratory measurements observing different light sources: data taken during a high altitude balloon flight over Canada, laser pulses observed from the ground traversing the real atmosphere, and model landscapes reproducing realistic aspect ratios and light conditions as would be seen from the ISS itself. The first level trigger logic successfully kept the trigger rate within the permissible bounds when challenged with artificially produced as well as naturally encountered night sky background fluctuations and while retaining events with general air-shower characteristics.

    The velocity of neutrons from a pulsed neutron source is well defined as a function of their arrival time. An electro-magnetic neutron accelerator/decelerator synchronized with the neutron time-of-flight is capable of selectively changing the neutron velocity and concentrating the velocity distribution. The possible enhancement of the neutron intensity at a specific neutron velocity by orders of magnitude is discussed, together with an experimental design.

    Ultra-cold neutron (UCN) is attractive for a search of the neutron electric dipole moment (nEDM). It is crucial to store UCNs with high density in a bottle for nEDM measurement apparatus. To increase the density, time focusing technique can be useful, where slow neutrons are accelerated and fast neutrons are decelerated by using magnetic potential. This device is called rebuncher. The rebuncher consists of a gradient magnet, RF coil, and neutron guide. The magnet generates a field gradient of 3.5 T/m (from 1 T to 0.2 T within 24 cm) in the longitudinal direction. By using anisotropic inter-poles, the magnet is compact and keeps the gradient uniform. The fabricated magnet showed good performance as designed. © 2012 IEEE.

    本研究ではミュー粒子にかかわる相互に関連した二つの精密測定研究を実施する。一つはこれまでの実績の発展として、2体束縛系であるミュオニウム(正ミュオンと電子の束縛系)の磁場下でのゼーマン副準位を高精度で測定することで、従来より一桁以上高い精度でミュオニウムの超微細構造および、ミュオンの磁気モーメントと質量を決定する。もう一つは、超低速ミュオンビームとペニングトラップの手法を組み合わせることにより、単一粒子ミュオンの測定を新たに開始し、ミュオンの磁気モーメントと質量をミュオニウムとは全く独立に、最高精度で決定する。これらの結果を総合し、素粒子標準理論を超えた新物理の探索を行う。
    素粒子標準模型は物質の基本構成要素とそれらの力学を記述するもので、ヒッグス粒子の発見により理論的だけでなく実証的にも完成した。しかし、模型のパラメタが多すぎることや、暗黒物質の担い手となる粒子が含まれていないことなど、数多くの問題を内包している。それらを解決する素粒子標準模型を超える新物理は必ず存在する。その兆候を探す有効な手段として、本研究では、測定の精度を究極まで高めるという実験手法を採用する。ミュオンはほどほどの質量と寿命を持ち、標準模型の検証、そして新物理を探索するプローブとして最適である。長く、世界各地でミュオン研究が行われているが、ミュオン自身そしてミュオンを含む物理現象に、素粒子標準模型では説明が困難なものが複数観測されている。本研究では、ミュオン、特にそのスピンに関する周波数精密測定を複数の物理系で行い、ミュオン粒子そのものの実験的理解を究めることで、新物理探索を目指す。
    [ミュオニウム]これまでの実績の発展として、ミュオニウム(正ミュオンと電子のクーロン束縛系)の磁場下でのゼーマン副準位の高精度測定を実施する。すでに磁場のない状態での基底状態超微細構造測定において、最高精度を達成している。さらに磁場のある状態での測定を実施することで、一桁以上高い精度でのミュオニウムの超微細構造(1ppb)およびミュオンの磁気モーメントと質量(ともに5ppb)を決定する。
    [ミュオントラップ]ミュオンを電磁トラップ(ペニングトラップ)で捕獲し、トラップ内でのミュオンの運動を観測する。ミュオンペニングトラップは世界初の挑戦で、超低速ミュオンビームを大量に生成できる日本のJ-PARCでのみ可能な実験である。ミュオンの磁場下での周回周波数を測定することで、ミュオンの磁気モーメントと質量を最高精度(2ppb)で決定する。
    本研究では究極の目標として、ミュー粒子(ミュオン)にかかわる相互に関連した二つの
    精密測定研究を実施する。一つはこれまでの実績の発展として、2体束縛系であるミュオニウム(正ミュオンと電子の束縛系)の磁場下でのゼーマン副準位を高精度で測定することで、従来より一桁以上高い精度でミュオニウムの超微細構造(1ppb)および、ミュオンの磁気モーメントと質量を(約5ppb)で決定する。もう一つは、超低速ミュオンビームとペニングトラップの手法を組み合わせることにより、単一粒子ミュオンの測定を新たに開始し、ミュオンの磁気モーメントと質量をミュオニウムとは全く独立に、最高精度(2ppb)で決定する。これらの結果を総合し、進行中のミュオニウム1s-2sエネルギー準位差測定、ミュオン異常磁気能率(Muon g-2)測定との比較、様々な理論モデルとの照合によって、素粒子標準理論を超えた新物理の探索を行う。
    本年度は各種要素技術開発に集中し、以下の成果を得た。1)超伝導電磁石磁場一様性の確保のための磁性流体を用いたシミング手法の確立。2)磁場一様分布の測定のためのNMRプローブアレイの予備機製作。3)3HeNMRプローブの基礎開発のためのガラスセルの製作および3He準安定状態励起の確認。4)トラップの概念設計およびフルシミュレーション環境の構築。5)超低速ミュオン発生用の244nmレーザーの開発。
    またJ-PARCミュオン施設のパルス状ミュオンを用いた最初の結果を論文公表することができた。
    本研究の前提である、大強度ミュオンを供給するミュオン施設Hラインは順調に建設が進んでおり、予定よりは遅れたものの2021年度に確実にビームを出せる状況となった。我々としてはビーム供給後、速やかにまずはミュオニウム超微細構造の高磁場下での測定を開始すべく万全の体制で準備を進めてきている。現状実験実質関して困難はない。いっぽうすみやかに信頼できる物理量を提示するためにはいわゆるブラインドアナリシスの手法を確立することが重要であり、現在その検討を進めている。ミュオントラップについては現段階で概念設計は終了しており、今年度の実機製作に向けて実施設計を進める。関連する要素開発としてミュオニウムイオン化のレーザーを今年度中に完成しSラインでのその性能試験を行う。また3Heプローブの開発では実際に使用する高磁場マグネット中での光ポンピングを行い、現在確率しているH2ONMRプローブとの比較を行う。陽電子検出器についてはプロタイプの製作を行い、実環境下でのテスト実験を実施する。

    Applicability of neutron spin flip chopper to the suppression of the neutron velocity width in epithermal energy region was evaluated for the pulsed neutron beam from the spallation source of Japan Proton Accelerator Research Complex. The possible intensity was estimated in the energy range up to 200 eV mainly for the general application in material researches. The result was reported to KENS and the scientific merit is under discussion.
    Additional developments on epithermal neutron polarizer and advanced neutron guide with extremely large reflection critical angle are necessary for achieving the estimated performance. Both of these techniques are valuable common to general neutron researches and we are considering to start the development researches.

    Cold neutron beam line BL05 was constructed at J-PARC. Various experiments including precision measurement of neutron lifetime was started with the high quality beam, which is provided by using our neutron optical devices. Developments of the devices, for example, space-time focusing of ultra-cold neutrons, enables us to perform extremely high precision measurement for physics beyond the standard model. For material science, we also developed some new neutron spectrometers including focusing VCN-SANS and resonance NSE.
