Fusion-Yield Enhancement in Magnetized Laser-Driven Implosions

ORAL

Abstract

We have successfully demonstrated an enhancement of the fusion performance of a magnetized, laser-compressed inertial confinement fusion target. A spherical CH target with a 10-atm D$_{2}$-gas fill was imploded using the OMEGA laser in a polar-drive configuration. A seed magnetic field of 80 kG was embedded in the target, and was subsequently trapped and compressed by the imploding conductive plasma. As a result of the target hot-spot magnetization, the electron-radial heat losses were suppressed and the observed ion temperature and neutron yield were enhanced by 15{\%} and 30{\%}, respectively. This work was supported by the U.S. Department of Energy Office of Inertial Confinement Fusion under Cooperative Agreement No. DE-FC52-08NA28302.
