摘要
本文采用Monte-Carlo法对电子在V型微通道板行波选通分幅相机微通道板单通道中传输、碰壁及二次电子发射的整个过程进行了模拟.模拟结果印证了微通道板孔径、屏距、屏压等参量对相机动态空间分辨率影响的定性分析,揭示了斜切角以及微通道板Ⅱ上电压V2对相机空间分辨率的影响.计算还结果表明,对于V型微通道板分幅相机,可以不区分动、静态空间分辨率.
Monte-Carlo method was used to simulate the whole courses of electronic transportation, collision and secondary emission in a single channel of a picosecond X-ray framing camera with a V-type double MCP structure and by gating a microchannel plate. Influences of some parameters of the framing tube to the dynamic spatial resolution of the camera were qualitatively analyzed demonstrated. The influence of chamfer angle of MCP and the voltage applied on MCP2 to the dynamic spatial resolution of this type of framing camera were uncoveredwere present. The result of this simulation demonstrates that the dynamic and static resolution of this kind of framing camera are almost the same.
