Comparison of new SiPM devices for applications in High-Energy physics

Silicon Photo-Multipliers (SiPMs) are widely used as light detectors for the new generation of experiments dedicated to high energy physics. This motivates our goal to tested a number of recent devices from different manufacturers: Hamamatsu 13360-1350; Ketek PM1125; ONsemiconductors FC10035 and AdvanSid NUV4S-P. Particular emphasis has been given to measurements of dark counts and gain, performed at different temperatures by means of a climatic chamber (F.lli Galli model Genviro-030LC) within a temperature range from -60 °C to +60 °C. This allowed evaluating the temperature coefficient of all devices, which was found in agreement with expectations.
