摘要:
为提高分幅相机的时间分辨率，采用无增益微通道板（microchannel plate, MCP）代替有增益MCP研制分幅相机．利用Monte Carlo方法对无增益MCP的时间分辨特性、渡越时间弥散及空间分辨特性进行了理论研究．结果表明，无增益MCP的时间分辨率随着选通脉冲宽度的减小而提高，无增益MCP中电子的渡越时间弥散小于有增益MCP的渡越时间弥散．无增益MCP变像管的空间分辨率优于有增益MCP变像管的空间分辨率．因而，无增益MCP可以减小电子的渡越时间弥散，获得更好的时间分辨率．
Abstract:
To improve the temporal resolution of the framing camera, a non-gain microchannel plate (MCP) instead of a gain MCP is used to study the framing camera. The temporal resolution, the transit time spread, and the spatial resolution of the non-gain MCP are simulated by using the Monte Carlo method. The simulated results show that the temporal resolution of the non-gain MCP increases with the decrease of the gating pulse width. And the transit time spread in the non-gain MCP is lower than that in the gain MCP. Furthermore, the spatial resolution in the non-gain MCP is better than that in the gain MCP. Therefore, the non-gain MCP could reduce the transit time spread, and obtain the better temporal resolution for the framing camera.
