Abstract
We present preliminary results on a study of spatially resolved preheat of the rear of thin foils irradiated by laser (0.26 μm, 600 μs, 10 J). The record is done with a schwarzschild microscope made of two spherical multilayered mirrors coated to have the maximum reflectivity at normal incidence for the wavelength of 304 A (40 eV). The large aperture (0.2) and the high spatial resolution (~ 3 μm) of the device allow to perform a very precise record of the emissivity at 40 eV of the rear side of a thin laser heated foil. Results for different Z materials are presented.
