Appendix hard X-ray. The X-ray imaging system.

The X-ray imaging system
Some advantages of this setup are:
- location of the virtual slit near the plasma while taking full advantage of the same F# than the uport9 imaging system.
- decrease on the number of crystal/detector arms (to three) at the port plug end
- reducion of the constrains inside the port plug imposed by the 16 discrete lines of sight
- increase of spatial resolution

Neutronic analysis has been performed at Garching by Dr. Lida for the Uport9 X-ray system. No gamma ray neither heat deposition analyses have been adressed yet

•Radiation level at detector is acceptable.•Man access is to avoid at crystal location •Shield is required at crystal location which may increase the scattered flux at detector

Improvement 1 to cover gaps (about 15 deg. toroidal component)

Improvement 2 to cover gaps
Large and long spectometer arrangement
Probably to ambicious object size (degrades imaging quality)
