Abstract

Fast electrons produced by the irradiation of plane-layered targets with 1 mJ, 100 fs, 2. 1016 W/cm2 CPM dye laser pulses at 10 Hz have been diagnosed by the Kα emission which they cause at various depths in the targets. The fast-electron energy spectrum and the absolute energy deposition have been deduced from a detailed comparison of the measured data with the results of a Monte-Carlo code calculating the Kα yield, target heating and ionization balance from various fast electron distributions.
