In the Laboratory of High-Energy Physics, 16-channel prototypes of detectors (with SiPM readout produced by Ketek and Hamamatsu) were developed for their application in zero-degree calorimetry and for measuring the profile of a low-energy neutron beam. This paper presents the method for determining the voltage of the breakpoint of the noise characteristic of silicon photomultipliers in the multichannel detector and its temperature dependence in the range from 27.7°C to 39.1°C. The response of SiPM to the LED source of calibrated light pulses has been studied and the time resolution has been obtained.
