Abstract

The invention discloses a scintillator array structure, and a neutron detector employing the same. The structure comprises a plurality of scintillator layers, and the plurality of scintillator layers are stacked together to form the structure. The plurality of scintillator layers at least comprise two scintillator layers with different thicknesses. The scintillator array is formed by the stacking of the plurality of scintillator layers, and the structure is provided with scintillator layers with different thicknesses. Therefore, the structure can be suitable for the detection of different neutron energy spectrums, and effectively enlarges the detection range of the neutron energy spectrums.

Description

technical field [0001] The invention relates to a scintillator array structure and a detector including the scintillator array structure, in particular to a gradient stacked scintillator array structure and a neutron detector including the scintillator array structure. Background technique [0002] Neutron spectroscopy, especially fast neutron spectroscopy, is of great significance. One of the important aspects is the monitoring of the reactor, so as to grasp the operation of the reactor; another commonly used field is the detection of solar neutrons and cosmic rays, so as to study the characteristics and laws of solar activities, and it is of great significance to aerospace safety. The traditional measurement method is to use gas-filled proportional detectors such as He-3 tubes to measure, but this kind of detector is bulky, the measurement energy is low, and the particle reaction is discretized. An emerging measurement method is to use a solid-state detector composed of s...
