摘要：

Indirect-drive inertial confinement fusion makes use of cavities constructed of high atomic number materials to convert laser power into x-rays for ablatively driving an implosion capsule. Obtaining spatially uniform drive on the capsule requires a careful balancing between the laser absorption region (high drive) and the laser entrance holes (low drive). This balancing is made difficult because of plasma expansion, and the associated movement of the laser absorption region with time. This paper reports the first experimental demonstration of compensation for this motion by using different laser beams at different times, in agreement with modeling.
