A power generation device may include a radiation source, an emitter, and a collector. The emitter may be formed adjacent to the radiation source. The emitter may include a high-density material. The collector may be adjacent to the radiation source and include a low-density material. The emitter is between the radiation source and the collector. An insulator may be positioned between the emitter and the collector. An emitter of a nuclear battery and a method of forming an emitter of a nuclear battery are also disclosed.

Power generation devices, associated components, and methods

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.
