Abstract :
Summary form only given. The electron temperatures of various layered, cone-wire, and nail targets irradiated with the Vulcan petawatt laser (2 times1020 W cm-2) at the Rutherford Appleton Laboratory are determined through the analysis of extreme-ultraviolet XUV images. Two channels in the XUV system allow for time integrated, spectrally resolved images of XUV emission at photon energies of 68 eV and 256 eV. A comparison of the absolute intensities of these images with the radiation hydrodynamics code LASNEX facilitates a temperature map of the target.
