Abstract : X-ray imaging optics have been essential diagnostics in inertial confinement fusion (ICF) research. A micro pellet is irradiated by a giant multi-beam laser system. This pellet is imploded to create a thermonuclear fusion condition, making use of the inertia of the imploding pellet wall. It is of critical importance for ICF to measure nonuniformities at the implosion core or the laser spot in order to drive the pellet to a very high density. Such measurements require a spatial resolution of less than 1 micron. We have chosen to build a Schwarzschild type x-ray microscope with a magnification of 15. This x-ray microscope can be applied to fields other than laser fusion, such as lithography, biology' and medicine. This can be a powerful tool when coupled with laser plasma x rays(LAPLAX), since the high brightness and temporal resolution of LAPLAX is added to the high spatial resolution.
