Calibration of 122 SensL MicroFJ-60035 SiPMs and the Reduction of Optical Cross-Talk due to Coupled Light Guides. (2023). Revista Mexicana De Astronomía Y Astrofísica, 59(2), 379-388. https://doi.org/10.22201/ia.01851101p.2023.59.02.14

Abstract

Recent silicon photomultipliers (SiPMs) boast excellent production quality, eliminating the need for individual breakdown voltage calibration. We present measurements of cross-talk probability and relative gain for 122 SensL MicroFJ-60035-TSV SiPMs. These semiconductor photosensors have replaced photomultiplier tubes in many applications due to their single-photon resolution, insensitivity to magnetic fields, robustness, and cost-effective photon detection at lower voltages. Light guides expand SiPMs' small photosensitive area, and optical coupling reduces cross-talk probability compared to bare sensors at nominal bias voltage, as demonstrated in this study.
