In recent years, the price increase of 3 He has triggered the search for alternative neutron detectors. One of the viable options is a scintillation-based neutron detector. Usually, photomultiplier tubes (PMTs) are used in these detectors for photodetection. However, the increase in performance requirements such as the operability in magnetic field and spatial resolution necessitates an advanced neutron detector. Therefore, we developed a detector prototype with an active area of 13 cm × 13 cm using silicon photomultipliers (SiPMs). As compared to PMTs, SiPMs offer more compactness, more robustness, and a lower sensitivity to magnetic field. The final detector is aimed to be used in the future at the TREFF instrument of the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, Germany, for neutron reflectometry (NR). First measurements were carried out at TREFF and at the dedicated detector test instrument V17 at BER-II of HZB in Berlin, Germany. In this study, we report the results for detection efficiency, gamma discrimination, 2-D position resolution, count rate, and detection linearity.

“…This paper builds upon these findings by analysing the effect of cold neutron irradiation on timing performance of SiPMs. We measured and compared the time resolution of non-irradiated and irradiated (the ones from the previous campaign) SiPM arrays (SensL and Hamamatsu) for a few hundred photons events per laser pulse, which is roughly the number of photons expected to hit a pixel during a neutron event in our two dimensional position detector [10].…”
