Silicon Photomultiplier development for the Imaging Air Cherenkov and Fluorescence telescopes — •Hiroko Miyamoto¹, Masahiro Teshima¹, Boris Dolgoshein², Razmik Mirzoyan¹, Jelena Ninkovic¹, and Thomas Schweizer¹ — ¹Max-Planck-Institut fuer Physik, Muenchen, Germany — ²Moscow Engineering Physics Institute, Kashirskoe Shosse 31, 115409 Moscow, Russia

A Silicon Photomultiplier (SiPM) is a novel solid state photodetector which has an outstanding photon counting ability. The device has excellent features such as high Quantum Efficiency, good charge resolution, fast response (~100 ps), very compact size, high gain, very low power consumption with low bias voltages (30V~70V), and immunity to the magnetic field. In the last few years, UV sensitive SiPMs with a p-on-n structure have been developed by a few companies such as Hamamatsu, Photonique, Zecotek Photonics Inc., and institutes such as the MPI-HLL (Max-Planck-Institute for Physics - Max-Planck-Institute Semiconductor Laboratory) as well as the MPI-MEPhI (Max-Planck-Institute for Physics - Moscow Engineering Physical Institute). UV sensitive SiPMs are particularly promising for astroparticle physics applications in Imaging Atmospheric Cherenkov Telescopes (IACTs), such as MAGIC/MAGIC-II and CTA, and a space-borne fluorescence telescope, JEM-EUSO. The current status of the SiPM development by MPI-HLL, MPI-MEPhI, and the study of the application to the telescopes noted above will be reported.
