Abstract
A position-sensitive neutron detector (PSND) has been designed and tes ted as a module of a multi-detector array. ''Cross-talk'' effects, con tributing a major distortion factor for all closely packed neutron det ector systems, have been measured. It was established, using neutrons from the spontaneous fission of Cf-252 (setting neutron energy thresho ld at 0.7 MeV), that the distortions of neutron energy and of neutron angular distribution am insignificant (within the level of statistical accuracy). The influence of cross-talk on the coincidence counting ra te was measured to range from 48% to 16% for distances between detecto r's axes of 12 to 24 cm.
