一种长狭缝软X射线扫描相机系统
-
摘要: 介绍了一种长狭缝软X射线扫描相机系统。其有效工作面积达0.1mm×30mm，以满足宽频谱记录要求，通过优化变像管电子光学系统设计，尽可能地减小了时间畸变；提出利用计算机软件对残存时间畸变进行高精度校正的方法。动态测试表明，在2.5cm/ns的扫描速度下，其动态空间分辨率优于15Lp/mm，时间分辨率优于5ps。

Abstract: A new kind of long slit soft x-ray streak camera is presented in this paper. The camera has a large working area of 0.1mm 30mm. Time distortion of the camera is minimized by improving the design of the electro-optical system of soft x-ray streak tube. The dynamic test shows that the camera has a temporal resolution of 5ps and a spatial resolution of 15Lp/mm along the slit length of 30mm at the fastest sweep speed of 2.5cm/ns. A new time distortion correction theory and its application is also presented. -
