Abstract: Photomultiplier tubes (PMT) have been used extensively as the photodetector of choice in scintillation baseddetectors for cold and thermal neutrons. However, the limitations of PMT based scintillation neutron detectorssuch as their sensitivity to magnetic fields or their high operating voltages (> 1 kV) have triggered the search foralternative photodetectors for these applications. Silicon photomultipliers (SiPM) operate in the single photonregime, have lower operating voltages (∼20–70 V) than PMTs and are insusceptible to magnetic field. Additionalfeatures of the SiPMs like their low production cost, compactness and higher readout rates make them apotential candidate to replace the photodetector part in these developments. Therefore, we are developing ascintillation neutron detector based on SiPM technology. The detector prototype with an active detection area of13 cm × 13 cm 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 experiments. In this paper, we report the detector concept, itsdevelopment and the simulation results for design optimization.
