Radiation temperature scaling in indirect-drive hohlraums

The hohlraum radiation temperature is studied for Gaussian laser pulses of order of 1 ns. The simulation results show that for this kind of pulse, the self-similar law of the radiation hydrodynamics is also valid in its time- rising phase. The scaling of the hohlraum radiation temperature as a functi on of laser parameter, hohlraum size, and x-ray conversion efficiency is ob tained and the effect of laser entrance hole is included.
