Silicon Photomultipliers (SiPMs) Evolution and Space Applications

Speaker

Dr. Fabio Acerbi, Fondazione Bruno Kessler

Abstract

Silicon photomultipliers (SiPMs) are single-photon sensitive detectors that continue to attract increasing interest in several industrial and scientific applications that require fast detection speed, high sensitivity, compactness, insensitivity to magnetic fields and low bias voltages. SiPMs are becoming the detector of choice in many high-energy physics (HEP) experiments and for the readout of scintillators in gamma-ray detectors for space. In such applications, they receive a significant dose of particles (e.g. protons and neutrons) and X and gamma rays. In space applications, they are expected to endure particle doses in the order ofa  few 1011 particles/cm².
Given such big interest, SiPM technology has been continuously improved over the last years, with many specific customizations for the different applications, (e.g. for VUV light detection or to work at cryogenic temperatures). The effects of ionizing and non-ionizing radiation on the SiPM functional performance have also been studied in depth, with specific irradiation campaigns, to understand the main mechanisms and to design more radiation-tolerant SiPM technologies for future space instruments.
