Abstract

High accuracy imaging of thermal neutrons has been demonstrated with detectors having solid converters coated with secondary electron emitters and coupled to gaseous electron multipliers. The present work concentrates on study of the neutron detection efficiency of detectors equipped with composite CsI coated ⁶Li neutron converters. Monte Carlo simulations of the neutron conversion and the charged particle and electron emission processes permit to optimize the converter parameters. The experimental study of the detection efficiency is described in detail and the results are compared with the theoretical predictions.
