The Compact High Energy Camera (CHEC) is a camera-development project involving UK, US, Japanese and Dutch institutes for the dual-mirror Small-Sized Telescopes (SST-2M) of Cherenkov Telescope Array (CTA). Two CHEC prototypes, based on different photosensors are funded will be assembled tested in UK over next ~18 months. designed to record flashes light lasting from few hundred nanoseconds, with typical RMS image width length ~0.2 x 1.0 degrees, has 9 degree field view. physical camera geometry dictated by telescope optics: curved focal surface radius curvature 1m diameter ~35cm required. work both ASTRI GATE SST-2M structures include an internal LED flasher system calibration. first prototype multi-anode photomultipliers (MAPMs) second silicon (SiPMs or MPPCs). soon installed structure Mt.
