Abstract

A two-dimensional position-sensitive neutron detector (PSD) was constructed using a scintillator attached to a position-sensitive photo-multiplier with 100 mm diameter. Position determination is based on charge division. Spatial resolution, gamma sensitivity, linearity, temperature dependence and radiation shielding have been investigated. The shaping amplifiers used in the detection electronics were optimized. Two kinds of scintillators were examined: LiI(Eu) crystal and Li-glass. Concerning the gamma sensitivity and resolution, the best performance was obtained using the LiI. A spatial resolution with full width half maximum of 1.3(1) mm was measured. A good shielding against gamma radiation was found to consist out of three layers: 5 mm of boron rubber, 5 cm of lead and 5 mm of boron rubber. The influence of the temperature on the PSD signal output was measured and indicates that a stabilization is necessary. The PSD will be used in a time-of-flight neutron reflectometer.
