    The Cherenkov Telescope Array (CTA) is the next-generation ground-based observatory for very-high-energy gamma rays. One candidate design for CTA’s medium-sized telescopes consists of the Schwarzschild-Couder Telescope (SCT), featuring innovative dual-mirror optics. The SCT project has built and is currently operating a 9.7-m prototype SCT (pSCT) at the Fred Lawrence Whipple Observatory (FLWO); such optical design enables the use of a compact camera with state-of-the art silicon photomultiplier detectors. A partially-equipped camera has recently successfully detected the Crab Nebula with a statistical significance of 8.6 standard deviations. A funded upgrade of the pSCT focal plane sensors and electronics is currently ongoing, which will bring the total number of channels from 1600 to 11328 and the telescope field of view from about 2.7◦ to 8◦. In this work, we will describe the technical and scientific performance of the pSCT.

    We report a Fermi-LAT $\gamma$-ray analysis for the Chamaeleon<br />
    molecular-cloud complex using a total column density (NH) model based on the<br />
    dust optical depth at 353 GHz ($\tau_{353}$) with the Planck thermal dust<br />
    emission model. Gamma rays with energy from 250 MeV to 100 GeV are fitted with<br />
    the NH model as a function of $\tau_{353}$, NH $\propto$<br />
    $\tau_{353}^{1/\alpha}$ ($\alpha$ $\geq$ 1.0), to explicitly take into account<br />
    a possible nonlinear $\tau_{353}$/NH ratio. We found that a nonlinear relation,<br />
    $\alpha$$\sim$1.4, gives the best fit to the $\gamma$-ray data. This nonlinear<br />
    relation may indicate dust evolution effects across the different gas phases.<br />
    Using the best-fit NH model, we derived the CO-to-H2 conversion factor (XCO)<br />
    and gas mass, taking into account uncertainties of the NH model. The value of<br />
    XCO is found to be (0.63-0.76) $\times$10$^{20}$ cm$^{-2}$ K$^{-1}$ km$^{-1}$<br />
    s, which is consistent with that of a recent $\gamma$-ray study of the<br />
    Chamaeleon region. The total gas mass is estimated to be (6.0-7.3) $\times$<br />
    10$^{4}$ Msun, of which the mass of additional gas not traced by standard HI or<br />
    CO line surveys is 20-40%. The additional gas amounts to 30-60% of the gas mass<br />
    estimated in the case of optically thin HI and has 5-7 times greater mass than<br />
    the molecular gas traced by CO. Possible origins of the additional gas are<br />
    discussed based on scenarios of optically thick HI and CO-dark H2. We also<br />
    derived the $\gamma$-ray emissivity spectrum, which is consistent with the<br />
    local HI emissivity derived from LAT data within the systematic uncertainty of<br />
    $\sim$20%

    The Gamma-ray Cherenkov Telescope (GCT) is a candidate for the Small Size Telescopes (SSTs) of the Cherenkov Telescope Array (CTA). Its purpose is to extend the sensitivity of CTA to gamma-ray energies reaching 300 TeV. Its dual-mirror optical design and curved focal plane enables the use of a compact camera of 0.4 m diameter, while achieving a field of view of above 8 degrees. Through the use of the digitising TARGET ASICs, the Cherenkov flash is sampled once per nanosecond continuously and then digitised when triggering conditions are met within the analogue outputs of the photosensors. Entire waveforms (typically covering 96 ns) for all 2048 pixels are then stored for analysis, allowing for a broad spectrum of investigations to be performed on the data. Two prototypes of the GCT camera are under development, with differing photosensors: Multi -Anode Photomultipliers (MAPMs) and Silicon Photomultipliers (SiPMs). During November 2015, the GCT MAPM (GCT-M) prototype camera was integrated onto the GCT structure at the Observatoire de Paris-Meudon, where it observed the first Cherenkov light detected by a prototype instrument for CTA.

    The Cherenkov Telescope Array (CTA) is a forthcoming ground-based observatory for very-high-energy gamma rays. CTA will consist of two arrays of imaging atmospheric Cherenkov telescopes in the Northern and Southern hemispheres, and will combine telescopes of different types to achieve unprecedented performance and energy coverage. The Gamma-ray Cherenkov Telescope (GCT) is one of the small-sized telescopes proposed for CTA to explore the energy range from a few TeV to hundreds of TeV with a field of view greater than or similar to 8 degrees and angular resolution of a few arcminutes. The GCT design features dual-mirror SchwarzschildCouder optics and a compact camera based on densely-pixelated photodetectors as well as custom electronics. In this contribution we provide an overview of the GCT project with focus on prototype development and testing that is currently ongoing. We present results obtained during the first on-telescope campaign in late 2015 at the Observatoire de Paris-Meudon, during which we recorded the first Cherenkov images from atmospheric showers with the GCT multi-anode photomultiplier camera prototype. We also discuss the development of a second GCT camera prototype with silicon photomultipliers as photosensors, and plans toward a contribution to the realisation of CTA.

    The future ground-based gamma-ray observatory Cherenkov Telescope Array (CTA) will feature multiple types of imaging atmospheric Cherenkov telescopes, each with thousands of pixels. To be affordable, camera concepts for these telescopes have to feature low cost per channel and at the same time meet the requirements for CTA in order to achieve the desired scientific goals. We present the concept of the TeV Array Readout Electronics with GSa/s sampling and Event Trigger (TARGET) Application Specific Circuit (ASIC), envisaged to be used in the cameras of various CTA telescopes, e. g. the Gamma-ray Cherenkov Telescope (GCT), a proposed 2-Mirror Small-Sized Telescope, and the Schwarzschild-Couder Telescope (SCT), a proposed Medium-Sized Telescope. In the latest version of this readout concept the sampling and trigger parts are split into dedicated ASICs, TARGET C and T5TEA, both providing 16 parallel input channels. TARGET C features a tunable sampling rate (usually 1 GSa/s), a 16k sample deep buffer for each channel and on-demand digitization and transmission of waveforms with typical spans of similar to 100 ns. The trigger ASIC, T5TEA, provides 4 low voltage differential signal (LVDS) trigger outputs and can generate a pedestal voltage independently for each channel. Trigger signals are generated by T5TEA based on the analog sum of the input in four independent groups of four adjacent channels and compared to a threshold set by the user. Thus, T5TEA generates four LVDS trigger outputs, as well as 16 pedestal voltages fed to TARGET C independently for each channel. We show preliminary results of the characterization and testing of TARGET C and T5TEA.

    In this research we achieved two main results for the Cherenkov Telescope Array (CTA) project, the next-generation ground-based gamma-ray observatory, to be built in 2020s. The first result is the successful completion of our prototype CTA camera with 2048 silicon photomultiplier camera pixels for the CTA small-sized telescopes. It was installed on a CTA prototype telescope in Italy, and its first light was achieved in 2019. The second result is gamma-ray detection of the Crab Nebula with another CTA prototype camera and telescope for the medium-sized telescopes, that use similar technologies but with a larger mirror diameter. These results are important milestones proving that our camera and telescope designs are viable for CTA.

    We have developed a UV-transparent lens array system to improve the effective photodetection efficiency of multi-pixel silicon photomultiplier (SiPM) arrays. Array type SiPMs currently available in the market have dead area between adjacent pixels, resulting in about 15% photon loss. Putting a lens array on the SiPM surface can guide photons from the dead area to the sensitive area, enabling us to improve the gamma-ray detection efficiency of ground-based gamma-ray telescopes or to reduce the production cost of photodetectors. Our prototype lens array showed improvement of photodetection efficiency by 10 to 20% in the angle-of-incidence range of 0 to 70 degrees.

    We have developed a prototype hexagonal light concentrator for the Large-Sized Telescopes of the Cherenkov Telescope Array. To maximize the photodetection efficiency of the focal-plane camera pixels for atmospheric Cherenkov photons and to lower the energy threshold, a specular film with a very high reflectance of 92-99% has been developed to cover the inner surfaces of the light concentrators. The prototype has a relative anode sensitivity (which can be roughly regarded as collection efficiency) of about 95 to 105% at the most important angles of incidence.
