SXRI film data from OMEGA showing time progression of x-ray burnthrough. The views of the target are sketched around the data images. Photos of the target are shown above the film data. The hard x-ray channel has a pinhole image of the target; the images in the mirror channels are flipped horizontally from the pinhole image. The dashed vertical lines show the footprint of the thick Al filter used for the hard x-ray channel. The strips are fired every . Along a strip, the time between soft x-ray images is . A timing fiducial beam hits the back wall at (bottom strip, image).
Concept of the SXRI showing its four soft x-ray channels, its hard x-ray straight-through filter channel, and the four strip microchannel plate (MCP) x-ray framing camera. The tilt of mirrors towards TCC is exaggerated; the true tilts are 0.6° (2° mirrors) and 2.2° (3° mirrors).
SXRI as (a) designed and (b) built. Magnification can be changed from to by placing slits at appropriate distance from TCC (that is, by changing the nose cone).
(a) Filters can be designed to compensate for variation of optical gain along MCP. (b) Construction of filters that are in use and (c) approximate throughput of 2° and 3° channels based on preliminary calibrations with Henke source.
