Abstract

A neutron detector includes a photo sensor with an electrical signal output electrically connected with an electrical signal input node of an electrical signal amplifier circuit. A resistive load is electrically connected between the electrical signal input node and a reference voltage node. The resistive load is a smaller resistance than an open circuit input resistance of the electrical signal amplifier circuit at the electrical signal input node thereby reducing the effective input resistance of the amplifier as seen by the photo sensor's electrical signal output. The neutron detector includes a set of scintillation layers connected to a light guide that channels light to the photo sensor. Moderator material is applied around the set of layers reducing thermal neutron absorption within the detector and increasing detector efficiency.
