摘要：

A short-laser-pulse driven ion flux is examined as a fast ignitor candidate for inertial confinement fusion. Ion ranges in a hot precompressed fuel are, studied. The ion energy and the corresponding intensity of a short laser pulse are estimated for the optimum ion range and ion energy density flux. It is shown that a light-ion beam triggered by a few-hundreds-kJ laser at intensities of greater than or similar to 10(21) W/cm(2) is relevant to the fast ignitor scenario.
