Abstract

For monochromatic imaging applications the advantages of combining two bent crystals in one system are demonstrated in comparison to a single crystal. The investigation shows that considerable improvements in resolution and spectral selectivity can be achieved by successive reflections from two bent crystals. The x-ray imaging device can be designed to a compact optical device mounted with the detector to a single port of the experimental chamber. This type of arrangement is of particular interest to large laser facilities such as those at LLNL, ILE, and CEA where a high x-ray photon flux is available but the space available for diagnostics is restricted. A design for an experimental setup planned for imaging of indirect driven fusion experiments at Lauwrence Livermore National Laboratory will be discussed here as an example. In general, improvements of spatial resolution by a factor of about 4 and spectral selectivity by a factor of about 10 can be achieved.
