Position-sensitive detector of neutrons and nuclear fragments in the kinetic energy range of 10–200 MeV

Abstract

The design of the position-sensitive neutron detector being developed by the Alikhanov Institute for Theoretical and Experimental Physics is described, and results of the simulation of its properties are presented. Based on the test results of the first prototype, the spatial resolution has been improved, and the detector shape has been optimized. The principal limitation on the positioning accuracy for neutrons is obtained from results of computer simulation in the GEANT4 environment. The expected spatial resolution of the designed detector is <1.5 cm.
