Imaging atmospheric Cherenkov telescopes (IACT) for Gamma-ray astronomy are presently using photomultiplier tubes as photo sensors. An interesting alternative are so-called Geiger-mode avalanche photodiodes (G-APD). They promise an improvement in sensitivity and, important for this application, in ease of construction (size and weight), operation (power consumption) and ruggedness. They have...

A novel and still rapidly evolving device, Silicon Photomultiplier (SiPM) is opening a new possibility of particle detection in the field of nuclear/particle physics, material science and medicine. We have been working on an evaluation of basic characteristics of Hamamatsu MPPCs, Photonique SSPMs, Zecotek MAPDs, as well as an application for a scintillating fiber detector and Cherenkov...

High ohmic poly-silicon which is used as quench resistor in conventional Silicon photomultipliers (SiPMs) turns out to be an obstacle for light and is one of the most cost and yield driving technological issues. SiPM is becoming very good candidate for the replacement of conventional photomultiplier tubes and thus the development of these devices is very striking. We have proposed a new...

Silicon photomultipliers, whose main advantage over conventional photomultiplier tubes is the operation in high magnetic fields, have been considered as position sensitive, single photon detector in a proximity focusing RICH with aerogel radiator. A module, consisting of 64 (8x8) Hamamatsu MPPCS10362-11-100P silicon photomultipliers, has been constructed and tested with Cherenkov photons...

Multicell Geiger-mode APDs (SiPMs) experienced a fast development in the last years. SiPM based detectors where multiphoton detection is involved are becoming common, but the use of SiPMs for single photon applications is still problematic due to their high dark rate, which can be reduced by several orders of magnitude only by cooling. SiPM operation at low temperature is also very interesting...
