摘要
Silicon photomultiplier (SiPM) devices with improved parameters were recently introduced by several vendors. In addition to published manufacturer performance specifications, different research groups have reported on measurements of the available SiPMs in different operating conditions and using different test setups. In this work we performed a consistent set of test procedures for SiPM devices from various vendors, with focus on Time-of-Flight (TOF) PET detectors applications. SiPMs from Hamamatsu (HPK), SensL, Ketek, and Excelitas were tested. The same experimental setup and procedures were used for comparison of timing resolution for small (3×3mm2) and large (6×6mm2 or 4×6mm2) devices coupled to short (3×3×10mm3) and long (4×4×25mm3) LYSO crystals. The potential opportunities for TOF PET detectors are also evaluated.
