%X Scintillation based neutron detectors are prominent alternatives to 3He based gas detectors traditionally used for detecting cold and thermal neutrons in neutron scattering experiments [1]. In the recent years, photomultiplier tubes (PMTs) have been used as a technology of choice for this kind of applications due to their single photon counting abilities and relatively fast responses in the nanosecond range. However, the high voltage requirements (of some kV), the inability to operate in presence of magnetic fields, and the electromechanical complexity normally accompanying these developments have all limited their use. Silicon based solid-state detectors capable of single-photon counting at even shorter response times, as it is the case of silicon photomultipliers (SiPM) or SPAD arrays, additionally offering better neutron counting rates, relatively lower costs, and the possibility of modular design have the potential of becoming the photodetection technology of choice in these experiments. Recent investigations [2, 3], have motivated us to follow the approach of using SiPMs for visible light detection in neutron scintillation detectors and develop a detector prototype yielding an active area of 13×13 cm², based on a digital SiPM (Philips Digital Photon Counting, PDPC) technology. Our goal is to eventually reach a two dimensional spatial resolution of 1×1 mm2, and a neutron counting rate of above 20 Mcps/m². 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.
