Description
New hybrid avalanche photo-detector has been developed as a photon sensor for the Belle II RICH counter.
Single-photon response was investigated in the presence of a magnetic field and excellent performance was demonstrated. In addition, the radiation damage was studied in detail.
By building a prototype consisting of 6 photo-detectors, a test beam experiment was carried out. We successfully obtained a clear Cherenkov image and potentail pi/kaon separation power is expected to be more than 4 sigma at 4 GeV/c.
