US Patent 10267947 Signal stabilization and calibration for neutron detection

A neutron detection apparatus, method, and system includes a scintillation device that emits photons in response to received neutron energy incident on the device. A gamma radiation source, coupled to the scintillation device and configured to emit a reference energy, is also detected by the scintillation device. The reference energy has a different energy than the neutron radiation. A light sensor is coupled to the scintillation device. The light sensor receives and converts the emitted photons into an electrical signal comprising an indication of both the reference energy and the received neutron energy.
