Embodiments relate to an advanced fast and thermal neutron detector material composition with the properties useful for Special Nuclear Material (SNM) detection. Specific embodiments of the material composition result in two excimer scintillation light production mechanisms that provide two corresponding independent techniques for gamma discrimination; namely Pulse Shape Discrimination and Pulse Height Discrimination. A dual discrimination method, Pulse Shape and Pulse Height Discrimination (PSHD), can be implemented relying on both pulse height discrimination and pulse shape discrimination, and can allow the operation of large area, fast and thermal neutron detectors.

A timing apparatus and method for a radiation detection, measurement, identification and imaging system are disclosed. The apparatus comprises high-energy photon detectors (100), a light pulse signal generator (300) and an optical fiber (200). Each high-energy photon detector (100) comprises a scintillation crystal and optical-to-electrical conversion multiplying devices. The high-energy photon detectors (100) are all provided with light transmission holes. Light pulse signals are propagated to the scintillation crystals through the light transmission holes (400), then propagated to the surfaces of the optical-to-electrical conversion multiplying devices through the scintillation crystals, converted and multiplied by the optical-to-electrical conversion multiplying devices, and processed and read by an electronic circuit. The high-energy photon detectors (100) independent from each other acquire absolute time from the light pulse signals generated by the light pulse generator (300) and timing and calibration are performed between the independent high-energy photon detectors (100). Timing is achieved through the time at which the optical-to-electrical multiplication devices receive the light pulse signals, decoupling between the high-energy photon detectors (100) can be realized, the independence of the high-energy photon detectors (100) is ensured, and thus the system can use, increase or decrease the high-energy photon detectors (100) more conveniently.
