摘要： A neutron detection apparatus includes a neutron detector and an analyzer. The neutron detector includes a plurality of neutron detector assemblies, where each of the neutron detector assemblies includes a plurality of neutron detection devices. The neutron detector also includes a moderating volume. The plurality of neutron detector assemblies are disposed within the moderating volume so as to form a three-dimensional array of neutron detection devices within the moderating volume. The analyzer is communicatively coupled to each of the neutron detection devices of the plurality of neutron detector assemblies. The analyzer configured to receive one or more measured response signals from each of the neutron detection devices, and perform one or more analysis procedures to determine one or more characteristics associated with the one or more neutron sources based at least on the received one or more measured response signals.

摘要： A radiation detector to monitor the neutron flux of a nuclear reactor or other high-radiation environment, that can withstand the high temperatures and radiation fields of such environment, is provided. A small dielectric substrate with a low neutron-activation cross section is provided. The substrate is coated with a neutron conversion material, such as uranium oxide or thorium oxide. One or more substrates form a micro-sized detection cavity that is filled with a detection gas. A voltage is provided across anode and cathode wires in the detection cavity. A neutron absorbed in the conversion material may release reaction products into the gas, causing ionization of the gas which then produces a current or voltage signal. The small detector volume minimizes energy deposition into the detection gas by competing particles such as gamma rays, fast electrons, and beta particles, and therefore minimizes false counts while retaining large signals from neutron interactions.
