Beschreibungen/Notizen

• Three independent methods (extreme ultraviolet spectroscopy, imaging at 68 and 256 eV ) have been used to measure planar target rear surface plasma temperature due to heating by hot electrons. The hot electrons are produced by ultraintense laser-plasma interactions using the 150 J , 0.5 ps Titan laser. Soft x-ray spectroscopy in the 50 - 400 eV region and imaging at the 68 and 256 eV photon energies give a planar deuterated carbon target rear surface pre-expansion temperature in the 125 - 150 eV range, with the rear plasma plume averaging a temperature approximately 74 eV .
