Effect of strong magnetization on heat flow and shape of inertial fusion implosions

ORAL

Abstract

This talk reports on the observation on how a strong 500 kG applied B-field increases the mode-2 asymmetry in inertial confinement fusion implosions. We used directly-driven implosions with a drive anisotropy and an externally imposed B-field. The magnetized implosions exhibit a significantly increased mode-2 compared to reference experiments, with identical drive but with no applied field. The X-ray self emission images show a 2.5x higher P2 (Legendre polynomial) amplitude with a reduced compression in the direction transverse to the B-field. Strongly magnetized electrons (ωe τe >>1) restrict the transverse heat flow, causing the mode-2 anisotropy to increase with magnetization.
