   The new type of photodetector — Silicon Photomultiplier (SiPM) is presented. The SiPM consists of the array (matrix) of p-n-junctions (~103 mm-2) joint together on a common silicon substrate. Each p-n-junction working in limited Geiger mode with a gain 106, but SiPM in whole is analogue detector, because the SiPM output signal is a sum of the signals from p-n-junctions fired by photons. The main SiPM features are described and its performance is compared with other photodetectors.
