Abstract

The recording of the spatial structure of a high temperature plasma in the hard X-ray region is limited by the problem of shine-through associated with a thin aperture material, when fine resolution is required, as well as the low-emission flux from the plasma in the high energy spectral region. In this paper, the design and performance of a hard X-ray camera is presented to monitor plasma radiation structure emitting in a spectral region above 12 keV, using the slit-wire camera design. In a series of experiments on GIT-4, the camera was used successfully to identify the spatial structure of the hard X-ray emission from the plasma and demonstrated the existence of a sub-100 /spl mu/m diameter, cm long plasma column emitting in the 18-30 keV region.
硬x射线狭缝线照相机
高温等离子体在硬x射线区空间结构的记录受到细孔径材料在高分辨率条件下的透光问题以及等离子体在高能谱区的低发射通量的限制。本文介绍了一种用于监测等离子体辐射结构的硬x射线相机的设计和性能,该相机采用狭缝线相机设计,在12 keV以上光谱区域发射等离子体辐射结构。在GIT-4上的一系列实验中,成功地识别了等离子体硬x射线发射的空间结构,并证明了在18-30 keV区域存在一个直径低于100 /spl mu/m,长cm的等离子体柱。
