IMAGING OF LASER-IRRADIATED TARGETS AT A WAVELENGTH OF 33.8-ANGSTROM USING A NORMAL-INCIDENCE MULTILAYER MIRROR

The morphology of the 33.8 angstrom emission from laser-irradiated tar gets was studied using a concave mirror with a W/B4C multilayer coatin g. The mirror had peak normal-incidence reflectance of 1.8% at a wavel ength of 33.8 angstrom. The emissions from a variety of targets were i maged on film with a spatial resolution of 30 mum in the target plane. Radiatively heated, low-density plastic and silica foams, x-ray laser targets, and a gas-filled enclosure were imaged. Several targets were simultaneously imaged at wavelengths of 33.8 and 130 angstrom using t wo normal-incidence microscopes.
