Abstract

A neutron scintillation detector based on a position-sensitive photomultiplier has been developed for neutron spin echo and small angle neutron scattering measurements. This photomultiplier has good spatial resolution, less than 1 mm². The detection efficiency of gamma ray background is very low for using a thin ZnS/⁶LiF scintillator. The effective area of this detector is around 60 cm².
