Simulation Study on Hard X-Ray Detection Efficiency for Microchannel Plate
为提升硬 X 射线的探测效率,优化了微通道板对硬 X 射线响应效率的影响模型,在模型中充分考虑了微通道板多种材料参数、结构参数以及微通道板基底材料原子壳层间相互串扰等因素的影响.在此模型的基础上,分析了微通道板的基底材质、通道直径、通道间壁厚、通道板厚度等参数对其探测效率的影响.基于现有技术条件,给出了微通道板各参数的最优组合及相应的探测效率,结果表明,其对 50～200 keV 能段硬 X 射线的探测效率可以达到 45%以上.
An optimized influence model of the microchannel plate on the response efficiency of hard X-rays was developed to improve the detection efficiency of hard X-rays.This model incorporates relevant material and structural parameters of the MCP,and further accounts for the crosstalk effects among atomic shells of the substrate material.Based on this model,the influence of key parameters—including substrate material,channel diameter,inter-channel wall thickness,and overall plate thickness—on the detection efficiency was analyzed.Considering current technological constraints,optimal values for these parameters and the corresponding detection efficiency were determined.The results indicate that the detection efficiency for hard X-rays in the 50-200 keV energy range can exceed 45%.
