Abstract
A monochromatic x-ray frame imager with toroidally bent crystals has been developed for use in laser fusion experiments. It consists of two arrays of bent-crystals and a fast x-ray framing camera. Temporal resolution of 35 ps, spatial resolution of 10m, and spectral resolution of 10 eV have been simultaneously attained. This performance is sufficiently high to provide spatial profiles of monochromatic x-ray images of a laser implosion dynamical core. These data have allowed temporal evolutions of electron temperature and density profiles in the core to be obtained, for the first time, in combination with a novel experimental technology and analysis technique on x-ray spectroscopy.
