Abstract
The present invention provides a self-powered neutron detector in which the net contribution of current generated by external gamma radiation is largely equal to zero. A self-powered neutron detector comprises a centralized emitter core, an insulator surrounding the core, an electrically conductive collector surrounding the insulator, and a conduit connected to the emitter core and the collector for withdrawal of generated gamma current. A layer is positioned between the emitter core and the insulator which consists of a material having a high atomic number, a low neutron activation cross section, and a thickness of at most about 5 microns.
