Abstract
36 elemental targets, beryllium through uranium, were irradiated with 8‐nsec FWHM Nd : glass laser pulses focused to ∼4×1013 W/cm2. X‐ray spectra were recorded with a convex‐crystal spectrograph and with a 22‐channel PIN‐diode spectrometer. Line and continuum spectra indicated temperatures of 36589 eV. Total x‐ray irradiances in the energy range 0.7–20 keV showed strong peaking as a function of atomic number with a maximum conversion efficiency of 9.6% relative to the incident laser energy. An indication of enhanced N‐shell x‐ray emission near U is reported here for the first time.Keywords
