Abstract

Intense thermal x rays with a brightness temperature up to 130 eV have been generated by focusing the iodine laser ASTERIX IV (200 J/400 ps at 0.44 micrometers wavelength) into 1 mm diameter spherical microcavities. The intense radiation has been used to study the radiative heating of low-Z material by replacing a gold wall element by a carbon foil. We performed measurements of the re-emission and the radiative burnthrough by time-resolved x-ray spectroscopy in the sub-keV spectral range at a resolution of 0.1 nm. The results are compared with MULTI simulations.
