AB  - In recent years, the price increase of 3He 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, with increase in performance requirements, such as operability in magnetic field and spatial resolution, a need for an advanced neutron detector arises. Therefore, we developed a detector prototype with an active area of 13 cm × 13 cm using Silicon photomultipliers (SiPM). As compared to PMTs, SiPMs offer more compactness, more robustness and 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 work, we report the results for detection efficiency, gamma discrimination, two dimensional position resolution, count rate and detection linearity.
