| 摘 要： | 一、前言 研究一个装置(例如等离子体焦点装置)发射X射线的物理过程,常需要拍摄不同时刻X射线发射源的图象。用微通道板可以制成这种探测系统,拍摄时空分辨的X射线图象。我们研制成的探测系统包括:微通道板(简写为MCP)真空系统;高电压毫微秒脉冲电源;同步系统;操作系统等。并在等离子体焦点装置上拍摄了从-161ns到+56ns时间间隔内6帧X射线发射源图象。每帧图象曝光时间为20ns。

| Abstract: | A microchannel plate detective system has been developed for measuring X-ray with time resolution. Using this apparatus, we measured x-ray emitted from the DPF-100 plasma focus device. Several x-ray pictures corresponding to distinct moments at the focus stage were obtained with an exposure time of 20 ns. |
