title: Bulk heating of solid-density plasmas during high-intensity-laser plasma interactions.
abstract: K -shell x-ray spectroscopy is used to study the interaction of small-mass copper foil targets (>20x20x2microm;{3}) with a high-intensity (>10;{19}Wcm;{2}) laser pulse. Efficient bulk heating to greater than 200eV is demonstrated using collisional-energy transfer from recirculating fast electrons. K -photon yields and bulk-electron temperatures calculated by three-dimensional numerical target-heating simulations are in good agreement with the experimental measurements.
