摘　　要：提出了一套近单色X光二维成像方案,即以掠入射反射镜与滤片组合作为软X射线分光元件,整合现有的二维分幅成像系统,因而最终构成带有一定能谱分辨能力的二维成像系统。该系统可以同时对Z-pinch内爆等离子体X光辐射的两个能谱区间进行监测,因此可以得到等离子体中不同温度物质的发展演化过程。通过更换滤片-反射镜组合,可以对200～1560 eV的X光子能量范围进行有选择性的探测。In this article a program of Quasi-monochromatic X-ray 2-dimension imaging is proposed through incorporation of a nanosecond framing camera and a soft X-ray energy separation device using grazing incidence mirror and filter. A conceptional 2-D imaging system with limited spectral resolution is constructed and can be applied to detect X-ray emission by Z-pinch implosion plasmas at two independent energy ranges.Thus the evolution of plasma materials with different temperatures can be studied with this technol...
