X-ray self-emission imaging with spherically bent Bragg crystals on the Z-machine

An x-ray imaging scheme using spherically bent crystals was implemented on the Z-machine to image x rays emitted by hot, dense plasma generated a Magnetized Liner Inertial Fusion (MagLIF) target. This diagnostic relies crystal capture emission over narrow spectral range (<15 eV), which is established limiting aperture placed Rowland circle. The spherical optic provides necessary high-throughput and large field-of-view required produce bright entire, one-cm length of emitting column plasma. average spatial resolution measured determined be 18 µm for highest configuration. With this resolution, radial size stagnation can accurately structures, such as bifurcations in column, are clearly resolved. success spherical-crystal imager has motivated implementation new, two-crystal configuration identifying sources line differential technique.
