Magnetohydrodynamics of high-energy-density-plasma in strong magnetic field

ORAL

Abstract

The magneto-hydrodynamics (MHD) of a high-energy-density-plasma (HEDP) in a strong external magnetic field contains a lot of fundamental and essential physics related to astro- and solar- physics and B-assisted inertial confinement fusion energy development. Especially, hydrodynamic instability in a strong magnetic field is a key physics for success of B-assisted inertial confinement fusion. Hydrodynamic instability growth is affected by strong magnetic field as a result of non-uniform heat flow. Experiments were conducted with a corrugated plastic target that is set between a pair of capacitor-coil. A pair of capacitor-coil targets was used to generate spatially uniform magnetic field. The plastic targets were irradiated by an intense laser pulse having 10$^{\mathrm{13}}$ W/cm$^{\mathrm{2}}$ of intensity. Temporal evolution of perturbation growth was observed with x-ray backlight technique. Enhancement of the perturbation growth in strong magnetic field was observed experimentally, and the result was consistent with hydrodynamic simulation.
