| 摘 要： | 利用双狭缝、透射光栅配亚仟X光条纹相机做了具有一维空间、时间和能谱分辨的三维软X光测量仪器(双狭缝透射光栅软X光时空分辨谱仪), 并成功地获得了金盘靶的N带X光(中心波长1.7nm)时空分辨图象 。该仪器空间分辨可达23μm, 时间分辨可达003ns, 能谱分辨(当源大小为100～300μm时对波长1.7nm的X光)可达0.4～ 0.7nm, 只需稍加改动, 即可用于其它波段的X光测量。

| Abstract: | A measure system, which is made up of double slits, a transmission grating and a soft X ray streak camera, has been made for measuring an X ray image with time, space and spectra resolutions. With this system the N band X ray (the central wavelength at 1.7nm) spacetime resolved image of gold disk irradiated by 0.35μm laser has been obtained successfully. The system can achieve spatial resolution of 23μm, time resolution of 0.03nm, and spectral resolution of 0.4～0.7μm for the X ray at 1.7nm wavelength if the size of X ray source is 100～ 300μm. The system can also measure the X ray at the other spectral bands． |
