摘要
报道了时间分辨的三通道软X射线光谱仪研制工作,重点介绍了研制的三通道能谱仪的工作原理以及210eV,420eV和900eV三个能区的设计参数,谱仪在上海神光Ⅱ高功率激光器三倍频实验中进行了多次实时考核,取得较好实验结果,将多道平面镜、滤光片成功配接于高时间分辨X射线条纹相机上,使该谱仪在亚千电子伏能区内,可同时进行三个波段软X射线的时间和空间分辨测量,提供的实验结果也表明:X射线平面镜结合滤光片的分光技术可应用于高时间分辨的X射线条纹相机上,从而获得高达10ps的时间分辨.
Developing of a time-resolved three-channel soft X-ray spectrometer is reported, and the operating principle and the parameters of spectrometer designed in three energy bands of 210eV, 420eV and 900eV are presented specially. On the ShenGuang- Ⅱ high power laser facility, the spectrometer was applied in experiments with good results. This work is the first attempt in China to constrtlet a spectrometer which couples planar mirrors and filters to X-ray streaked camera, and which is capable of measuring X-ray signal with spatial- and temporal-resolution in three sub-Key energy channels simultaneously. Experimental results show that by combining X-ray reflector and filter, the spectrometer has achieved enery resolution of 5 and temopral resolution ability of 10 ps.
