将聚乙烯慢化球划分成多个壳层,19对~6Li-~7Li玻璃闪烁体探测器布置于各壳层,通过三维空间内不同位置的热中子探测,达到类似中子多球谱仪对于不同能量中子的慢化效果,以实现位置灵敏探测功能。由于~6Li-~7Li玻璃闪烁体组合探测器具有n、γ甄别功能,该探测器可用于混合场中子能谱测量。采用MCNP程序初步模拟计算了该单球中子谱仪的响应。聚乙烯球直径为30 cm,采用美国 Polyethylene moderating sphere is divided into several shell layers. Nineteen pairs of 6Li ~ 7Li glass scintillator detectors are arranged in each shell layer. Through thermal neutron detection at different positions in the three-dimensional space, Instrument for different energy neutron moderation effect, in order to achieve the location of sensitive detection. The detector can be used for mixed-field neutron spectroscopy because of the n, γ discrimination of ~ 6Li- ~ 7Li glass scintillator combination detectors. The MCNP program was used to simulate the response of the single-ball neutron spectrometer. Polyethylene ball diameter of 30 cm, using the United States
