Paper Abstract

A new design for a position-sensitive detector system for thermal neutrons is introduced. The detection principle with a thin 6LiF converter on the surface of a semiconductor diode is described. In experiments with thermal neutrons, a spatial resolution of 1.25 mm was obtained. The detector is insensitive to (gamma) -rays with energies up to 1.5 MeV. The design of a detector with an improvement of the detection efficiency for thermal neutrons from 2.5 percent up to 35 percent is also proposed and the present state of the process development for its fabrication is described.
