摘要: 对微通道板(Micro-Channel Plate,MCP)的电子输运特性进行仿真研究.利用数值方法分析微光像增强器电子光学系统,得到电场分布.通过电场分布追踪MCP电子运动轨迹,确定电子在荧光屏像面上的落点分布.据此研究MCP电子输运,分析斜切角、通道直径及两端电压对电子输运、像增强器调制传递函数(Modulation Transfer Function,MTF)及分辨率的影响.结果显示,当MCP斜切角为14°、通道直径为5.0μm、两端电压为900 V时,MCP具有良好的电子输运特性,像增强器MTF特性好,分辨率高.

关键词: 微通道板, 电子输运, 调制传递函数, 分辨率

Abstract: To improve resolution of a low-light image intensifier,simulation of electronic transport in a micro-channel plate(MCP) is made.Field distribution is obtained by calculating electron optics with numerical method.Distribution of photoelectron on fluorescent screen is determined by tracing electron trajectory in MCP.Influence of MCP tilt angle,channel diameter,voltage on electronic transport and resolution of image intensifier are studied.It shows that MCP has good electronic transport characteristics,image intensifier has good modulation transfer function(MTF) and high resolution at a title angle of 14°,channel diameter of 5.0 μm,a voltage of 900 V.

Key words: MCP, transport of electrons, MTF, resolution
