ENERGETICS OF INERTIAL CONFINEMENT FUSION HOHLRAUM PLASMAS

We present the first measurements of radiation temperatures and stimul ated scattering losses in laser-driven, gas-filled hohlraums. They sho w efficient coupling when applying laser beam smoothing techniques. Sc attering losses are reduced to the 3% level while the radiation temper atures increased by similar to 15 eV for smoothed laser beams. We obse rve peak radiation temperatures in excess of 230 eV in gas-filled hohl raums consistent with detailed hydrodynamic LASNEX modeling.
