Foil targets irradiated by the Naval Research Laboratory Nike KrF lase
r were imaged in the x-ray region with two-dimensional spatial resolut
ion in the 2-10 mu m range. The images revealed the smoothness of the
emission from target and backlighter foils, the acceleration of the ta
rget foils, and the growth of Rayleigh-Taylor instabilities that were
seeded by patterns on the irradiated sides of CH foils.
