摘要/Abstract

摘要： 模拟计算了集成式多球中子谱仪7路测量通道同时工作与每路测量通道独立测量时的能量响应函数。两种测量模式的能响比值结果显示,球球干扰的影响随着慢化球尺寸增大而减小;对小尺寸慢化球球球干扰随着中子能量增大而增大。

Abstract: The energy response ratio of the integrated multi-sphere neutron spectrometer when the seven measurement channels work simultaneously and each measurement channel works separately is calculated. The results of the energy response ratio of the two measuring modes are displayed the influence of the sphere-sphere interference decreases with the increase of the size of the slowing sphere, and the interference of the small-size slowing sphere increases with the increase of the neutron energy.

Key words: Integrated multi-sphere neutron spectrometer, sphere-sphere interference, energy response
