The photon detectors have today a large range of applications from high energy physics (e.g. scintillator read-out in calorimetry) to astrophysics (e.g. time of flights studies) and nuclear medicine (e.g. scintillator read-out in PET analysis). Silicon PhotoMultiplier (SiPM) is a progressively developing solid state photodetection device. It has many properties comparable to or better than conventional photon detectors used today (e.g. photomultiplier tubes, hybrid photodetectors, avalanche photodiodes). Mainly, SiPM is promising for the detection of light with very low intensity when there is a magnetic field and where space and power consumption are limited. The main characteristics of the SiPM devices in comparison with those of the conventional photon detectors will be described. In particular, the characteristics of the first SiPM prototypes developed at ITC-irst will be presented.
