Goldstein, N P; Todt, W H

An improved compensated self-powered neutron detector is detailed wherein a thin conductive layer of low neutron cross section, high density material is disposed about the emitter core and also on the interior of the collector sheath. The conductive layer about the emitter absorbs low average energy electrons produced by emitter material activation products. The provision of the inner and outer conductive shield layers insures that signal current due to the response of these shielding layers to external gamma rays will be nullified and the detector device compensated to provide a detector which primarily responds to neutrons.
