Outline of Final Research Achievements

Silicon photomultiplier (SiPM) has intrinsically high photon efficiency. We have verified that a dense array of SiPM satisfy requirements for a photosensor of a Cherenkov telescope. In addition, we have developed application specific integrated circuits (ASICs) for high speed waveform recording in order to process signals from a dense array of SiPMs. We have built a prototype camera using those ASICs and installed in a prototype Cherenkov telescope. Using this prototype telescope, we have verified the performance of the camera in the real-life environment by successfully taking images of air showers produced by cosmic rays.
