Abstract

Abstract We describe the design and performance of a 157 mm×157 mm two dimensional neutron detector. The detector uses the Anger principle to determine the position of neutrons. We have verified FWHM resolution of <1.2 mm with distortion <0.5 mm on over 50 installed Anger Cameras. The performance of the detector is limited by the light yield of the scintillator, and it is estimated that the resolution of the current detector could be doubled with a brighter scintillator. Data collected from small (<1 mm3) single crystal reference samples at the single crystal instrument TOPAZ provide results with low values of the refinement parameter Rw(F).
