-
摘要: 介绍了扫描型皮秒X射线分幅相机的分幅原理,主要技术指标的测试方法和结果。相机的动态空间分辨优于61p/mm,最短曝光时间75ps(FWHM),触发晃动(80%发次)小于±30ps,几何畸变小于±5%,达到现场实验诊断的要求。Abstract: The operational principles, dynamic measurement and experimental results of a picosecond X-ray framing camera are described in this paper. The experiments have shown that this camera can provide 3 frame images with exposure time 75ps (FWHM), interframe time 150ps. Dynamic spatial resolution is better than 61p/mm, trigger jitter time for 80% shots<±30ps, and geometric distortion < ±5%.
