摘要
研制了一种双MCP近贴单幅相机 ,相机用于软X射线光谱探测 采用开放式无窗结构 ,利用第一块通道板进行选通 ,有效探测面积Φ 2 6mm 相机时间分辨率 5ns ,静态空间分辨率2 5lp/mm ,动态空间分辨率 7lp/mm ,控制电路固有延时小于 2 0ns .主要介绍了该相机的结构、工作原理、快门脉冲发生器电路。
A windowless soft x-ray double-MCP single frame camera is developed. The first MCP (Φ26 mm) is used to control the pass of electrons. The camera has a temporal resolution of 5ns, a static spatial resolution of25 lp/mm, a dynamic spatial resolution of 7 lp/mm. The controller has an intrinsic delay time of less than 20 ns and 500 ps time jitter. The camera′s configuration, work principle, time gating pulse generator, applied condition and its performance are introduced mostly in this paper.
