17 Feb 2019 | | Abstract: | The gain of silicon photomultipliers (SiPMs) increases with bias voltage and
decreases with temperature. To operate SiPMs at stable gain, the bias voltage
can be readjusted to compensate for temperature changes. We have tested this
concept with 30 SiPMs from three manufacturers (Hamamatsu, KETEK and CPTA)
operating in a climate chamber at CERN by varying temperatures between $1^circ
m C$ and $48^circ
m C$. We built an adaptive power supply that uses a
linear dependence of the bias voltage on temperature. We stabilized four SiPMs
simultaneously with only one compensation parameter for the readjustment of the
bias voltage of four SiPMs. For all tested Hamamatsu and CPTA SiPMs we achieved
our goal of limiting gain changes to less than $pm 0.5\%$ in the $20-30^circ
C$ temperature range. | | Source: | arXiv, 1902.6261 | | Services: | Forum | Review | PDF | Favorites | |
