A Multi-Layer Silicon Neutron Detector for Discrimination
Abstract
A neutron detector based on a multi-layer silicon proton recoil detection scheme is under development. The neutron detector uses polyethylene sheets as a neutron convertor and a stack of three silicon wafers to detect the recoiling protons. The multi-layer silicon detector features variable threshold for low energy neutrons, nominal 2 pi directional response, and low sensitivity to gamma rays. Pulse processing electronics has been developed to analyze signal events in real time to determine the direction of the incoming neutron. The multi-layer silicon sensor system has been tested under various neutron and gamma radiation conditions. The sensor efficiency and angular response have been measured for 15 MeV monoenergetic neutrons.
