Progress in the shock-ignition inertial confinement fusion concept

Shock-ignition experiments with peak laser intensities of ~8 x 10 super(15) W/cm super(2) were performed. D sub(2)-filled plastic shells were compressed on a low adiabat by 40 of the 60 OMEGA beams. The remaining 20 beams were delayed and tightly focused onto the imploding shell to generate a strong...

Zusammenfassung:Shock-ignition experiments with peak laser intensities of ~8 x 10 super(15) W/cm super(2) were performed. D sub(2)-filled plastic shells were compressed on a low adiabat by 40 of the 60 OMEGA beams. The remaining 20 beams were delayed and tightly focused onto the imploding shell to generate a strong shock. Up to 35% backscattering of laser energy was measured at the highest intensity. Hard x-ray measurements reveal a relatively low hot-electron temperature of ~40 keV, independent of intensity and spike onset time.
