Compensation of the temperature fluctuations in the silicon photomultiplier measurement system

This paper presents the method for the compensation of the temperature fluctuations in the measurement system based on the Silicon Photomultipliers. The system was created by the authors of the paper. Temperature has very strong influence on the gain of the detectors. Because single photons are detected and the system is very sensitive, its parameters has to be steady during the measurements. Temperature is being stabilized by changeable bias voltage of the detector. This paper describes how the algorithm of compensation has been determined during series of measurements and calculations.
