摘要

Measurements of the total energy carried by fast ablator-ions in direct-drive implosions on OMEGA have been conducted using magnetic and Thomson Parabola spectrometers. It is shown that the total laser energy lost to fast ablator-ions for plastic and glass targets is comparable and that it is a modest fraction of the incident laser energy (≤1%). These measurements have been used to infer a non-linear, voltage-dependent target capacitance (~0.1 nF) associated with the space-charge that accelerates the fast-ions.
