Abstract
- Many characteristics of Silicon Photomultipliers can be tuned with temperature and operation voltage. We present preliminary results of a study of the effect of these two operation parameters on the time resolution of large active area Multi-Pixel Photon Counters (MPPCs) manufactured by Hamamatsu. Measurements at -10 C, 0 C, and 10 C at different bias voltages were performed. The time resolution is best at low temperature and high over-voltage. Most significant improvements can be achieved in cases with low number of fired pixels (<10 pixels). Between the worst and best case among the considered conditions a factor of 5 improvement was observed. In cases with large number of fired pixels (>40 pixels) the effect of temperature and operation voltage becomes smaller. The timing performance still improves with decreasing temperature (~ factor of 2) but it hardly depends on the operation voltage. The study shows, that especially in applications where only few photons are available for detection a careful optimization of temperature and operation voltage are advisable to obtain optimum timing results with the MPPC.<br />Comment: Proceedings paper for SORMA 2010 conference
