摘要：

The maximum gain attainable from fast-ignited direct-drive implosions is derived based on realistic target designs and laser pulses, one-dimensional simulations of the implosion, and two-dimensional simulations of ignition by a collimated electron beam and burn propagation. Since the implosion characteristics are set by the optimized target design, the ratio of the thermonuclear energy to the compression laser energy is a unique function of the driver energy on target. It is shown that, if ignited, the fuel assembled by a 100-kJ UV laser can yield close to 6 MJ of thermonuclear energy. (c) 2006 American Institute of Physics.
