Abstract :
We have designed and developed the adaptive power supply to keep the gain of SiPMs in the analog hadron calorimeter of the CALICE Linear Collider detector stable at the level of 1%. This power supply compensates automatically the bias voltage for temperature variations in the range 5 °C to 40 °C. It operates in the voltage range 15 V to 90 V suitable for most of SiPMs on the market. We demonstrate the performance of the gain stability with a prototype that was produced in industry after measurements with a test board. We checked the gain stability for several types of SiPMs from three producers - Hamamatsu, KETEK and CPTA. This adaptive power supply can be easily used in applications beyond the calorimetry in particle physics.
