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.
