Abstract:

A thermal neutron detector comprises an enclosure containing a helium-xenon gas mixture, an optical fiber, and an electrode arranged to detect ion particles. The optical fiber detects photons generated by a reaction of the gas mixture with neutrons passing through the enclosure. The reaction also generates ion particles that are detected by the electrode. A coincidence detector generates an output signal corresponding to the correlation of ion detections from the electrode with photon detections from the optical fiber, rejecting signals generated from the electric field that are not correlated with photon detections.
