A demonstration study of focusing geometry small-angle neutron scattering (FSANS) experiment was successfully performed using a superconducting sextupole magnet as a neutron focusing device and a polarized cold neutron beam. The obtained small-angle neutron scattering intensities from monodispersed SiO <inf>2</inf> spherical particles were discussed in terms of the scattering function taking into account the q-resolution. © 2004 Elsevier B.V.

A system of a polarizing solid state bender and a collimator was built and tested. The bender consists of a stack of thin silicon wafers coated with polarizing FeCo-Si supermirrors. The stack is deflected in the middle by one wafer thickness. Inserted in an unpolarized neutron beam this device works as a spin splitter by transmitting the spin down component without any change in its flight path and reflecting the spin up component. With a collimator behind the bender it can be selected which one of the spin components is transmitted. In this way a transmission polarizer for neutrons with wavelengths above 4 Å was built which has a total length of less than 10 cm. © 2004 Elsevier B.V. All rights reserved.

We are developing a fiber type two-dimentional (2-D) position-sensitive detector having a spatial resolution less than 0.5 mm in order to use it in the time-of-flight (TOF) measurements. The detector performance was examined, and some experiments on the TOF radiography were performed using this detector. The results indicated that the detector could be applied successfully to the TOF measurement and that the TOF radiography was very useful since it gave more informative data than those obtained by the conventional radiography using a broad energy band. © 2005 IEEE.

The luminescence property of Ce-doped oxide glass having B and Li with large absorption coefficient for neutron was investigated by optical transmittance, alpha particle, and neutron irradiation. The light output of the B <inf>2</inf>O <inf>3</inf>-Li <inf>2</inf>O:CeO <inf>2</inf> glass system increased with the increase in B <inf>2</inf>O <inf>3</inf> and CeO <inf>2</inf>. It was observed that the decay time which showed composition dependence varied in the range 30-45 ns. Although the light output by neutron irradiation is 9.2% of Li-glass, low density and high neutron absorption with short decay time make this new boron-based glass scintillator useful for neutron detection.

With the Akeno Giant Air Shower Array (AGASA), we published the small-scale anisotropy of cosmic rays with energies above 1019 eV. Among them, a broad cluster - BC1 around (20h 50m, 32°) - has interesting characteristics: The time distribution of members of the BC1 cluster is burst-like around MJD50000 , and this cluster locates near the famous supernova remnant: the Cygnus Loop. From this BC1 direction, two observations from the Tibet and Milagro experiments have been reported. In this report, we summarize the results from the whole observation time of AGASA and the Akeno 1km2 array experiment, and the relation with the observations from the Tibet and Milagro experiments is discussed.

The focal surface of the EUSO telescope consists of a few hundred thousand of pixels of photo-detectors and detects air showers as mosaic images. The strongest requirement for the focal surface detector is the maximization of the photon detection efficiency together with the uniformity over the focal surface. We have developed a new type of multi-anode photomultiplier tube (MAPMT). The tatal photon detection efficiency has improved than before by about 2.1 times.

The Focal Surface detector of EUSO (Extreme Universe Space Observatory) consists of small autonomous functional units (elementary cell, EC) assembled in larger modules (Photo Detector Modules, PDM). Each EC is conceived as an array of 4 multianode photomultipliers (MAPMTs). We have developed EC structure for the current baseline of the multianode photomultiplier (MAPMT, R8900-M36). As the mechanical characteristics of the PDM structure (e.g. robustness to thermal and launch shocks, vibrations at launch) will affect the EC structure, we have also built a trial PDM, consisting of 36 MAPMTs (9 ECs) arranged in a cartesian layout. The purpose of such trial PDM is to develop and optimize the EC structure.

A neutron scintillation detector based on a position-sensitive photomultiplier has been developed for neutron spin echo and small angle neutron scattering measurements. This photomultiplier has good spatial resolution, less than 1 mm2. The detection efficiency of gamma ray background is very low for using a thin ZnS/6LiF scintillator. The effective area of this detector is around 60 cm2. © The Owner Societies 2005.

The chemical composition of ultra-high energy cosmic rays (UHECRs; > 1019 eV) is a key parameter to understand their nature and origin. In the Akeno Giant Air Shower Array (AGASA) experiment, we measured the muon density at 1000 m from the cores for 159 UHECR events. The data were interpreted by the recent CORSIKA simulation (version 6.203) with QGSJET01 and SIBYLL2.1 interaction models. The data is consistent with light components for the QGSJET model. No positive signature has been found for the gamma ray dominance. In the presentation at the conference we will report detailed results and comparisons with the results from other experiments.

EUSO-TA is a ground-based telescope, installed at the Telescope Array (TA) site in Black Rock Mesa, Utah, USA. This is the first detector to successfully use a Fresnel lens based optical system and multi-anode photomultipliers (64 channels per tube, 2304 channels encompassing a 10.6° × 10.6° field of view) for detection of Ultra High Energy Cosmic Rays (UHECR). The telescope is located in front of one of the fluorescence detectors of the TA experiment. Since its installation in 2013, the detector has observed several ultra-high energy cosmic ray events and, in addition, meteors. The limiting magnitude of 5.5 on summed frames (∼ 3 ms) has been established. Measurements of the UV night sky emission in different conditions and moon phases and positions have been completed. The performed observations serve as a proof of concept for the future application of this detector technology.
