The first test of a position‐sensitive photomultiplier in a thermal neutron diffraction topography experiment is reported: a spatial resolution was obtained of ≃200 μm in FWHM over a sensitive area of size ≃8 × 8 mm (≃1600 pixels) and a detection efficiency of the order of 15% when using a 0.25 mm thick ZnS–LiF (NE 426) scintillator. The advantages of this detector, its foreseeable improvements, and the scientific problems it could help to solve are discussed.
