Abstract:
1. A scintillation detector comprising: a photodetector; a first scintillating material configured to emit light in response to exposure to neutrons, the scintillating material having a first index of refraction; a second scintillating material having a second index of refraction that is less than the first index of refraction, the second scintillating material having a first surface disposed in optical contact with a surface of the first scintillating material and a second surface disposed in optical contact with a surface of the photodetector, the second scintillating material configured to transmit the emitted light; and a processor configured to perform: applying a filter configured to convert a pulse produced by one of the first and second scintillation materials into a unipolar pulse and convert a pulse produced by another of the first and second scintillation materials into a bipolar pulse; and identifying the constituent pulses corresponding to being produced by the first scintillating material and being produced by the second scintillating material based on the presence of positive and negative maxima.
