Abstract

The excellent production quality of recent generations of Silicon Photomultipliers (SiPMs) allows for operation without individual calibration of the breakdown voltage. Measurements of the crosstalk probability and the relative gain of 122 SiPMs of type SensL MicroFJ-60035-TSV are presented. Semi-conductor photo sensors have replaced photo multiplier tubes in numerous applications featuring single-photon resolution, insensitivity to magnetic fields, higher robustness and enhanced photo detection efficiency at lower operation voltage and lower costs. Light guides are used to increase the comparably small photo sensitive area of SiPMs. Their optical coupling changes the surface conditions of the sensor and influences the probability for crosstalk photons to leave the sensor without inducing secondary breakdowns. This study compares properties of sensors that are optically coupled to light guides with bare sensors, operated at nominal bias voltage. It demonstrates, that the optical coupling to a light guide significantly reduces the crosstalk probability of the measured sensors.

122传感器microfj-60035 sipms的校正及耦合光导引起的光串扰的减小

最近几代硅光电倍增管(SiPMs)的卓越生产质量允许在没有单独校准击穿电压的情况下运行。给出了122 SiPMs型SensL MicroFJ-60035-TSV串扰概率和相对增益的测量结果。半导体光传感器在许多应用中取代了光倍增管，具有单光子分辨率，对磁场不敏感，更高的鲁棒性和在更低的工作电压和更低的成本下增强的光检测效率。光导用于增加相对较小的sipm光敏面积。它们的光学耦合改变了传感器的表面条件，并影响了串扰光子离开传感器而不引起二次击穿的概率。本研究比较了在标称偏置电压下工作的光导光学耦合传感器与裸传感器的性能。结果表明，光导的光耦合显著降低了被测传感器的串扰概率。
