Evaluation of the dark signal performance of different SiPM-technologies under irradiation with cold neutrons

Performance of a Position-Sensitive Neutron Scintillation Detector Based on Silicon Photomultipliers

“…The SiPM has better performance characteristics than PMTs such as a lower operating voltage (∼25 V), a higher PDE (∼50%), and an insusceptibility to magnetic field. Concerning radiation hardness of SiPMs in cold/thermal neutron detection, our investigation shows that SiPMs have an expected lifetime of ten years of operation with an acceptable performance degradation for typical small-angle neutron scattering experiments [8], [9]. Hence, SiPMs can be a possible alternative to PMTs for such applications [10].…”

Development and characterization of a 4 × 4mm2pixel neutron scintillation detector using digital SiPMs

“…Recently, the effects on the photodetection performance of SiPMs have been examined quantitatively. The results indicate, that with typical neutron dosages in small angle neutron scattering (SANS) experiments, a lifetime of up to 10 years can be expected [4].…”

A Comparison of the Effects of Neutron and Gamma Radiation in Silicon Photomultipliers

“…These studies have all shown that neutrons with energies ∼ 1 MeV cause a significant increase in noise and leakage current that can lead to difficulties in using these devices in applications with high levels of neutron fluence. Additional studies have been carried out with thermal neutrons [16] which have shown similar effects, but only at very high fluences. There have been fewer studies on the effects of gamma ray irradiation on SiPMs [17]- [19], and those studies show a similar effect of increased leakage current with dose, but typically to a much lesser degree.…”
