New approaches for a 2D neutron detector based on ZnS:6LiF scintillator read out with WLS-fibers and SiPMs

Recently we reported on a high efficiency, low gamma-sensitivity, high count rate capable 1D neutron detector consisting of ZnS:6LiF scintillator readout with WLS-fibers coupled to SiPMs which showed a performance comparable with a 3He-based detector. In this work we discuss a possible extension of the developed technology to large area 2D detectors with high count rate capability suitable, for example, for the new generation of neutron powder diffraction instruments planned at the European Spallation Source.
