XUV and X-ray plasma diagnostics were performed on several relativistic electron beam generators. The data yield information on the spectral, temporal and spatial behavior of radiation in the 40 eV-6 keV range for the elements Al, Ti, Cr, Fe, and Ni as well as the noble gases Ne, Ar, Kr, and Xe. Temperatures, electron densities, and emitting volume of the plasmas were determined by direct
