Studies of preheat-induced mix in MagLIF targets

POSTER

Abstract

Magnetized Liner Inertial Fusion (MagLIF) is an inertial confinement fusion concept that preheats a magnetized fuel prior to compression and has the potential to reach high thermonuclear fusion yields. During the laser preheating stage, the higher-density liner material can blow off the liner wall and mix into the lower-density D2 fuel via x-ray ablation or impact from the late-time blast wave. Adding a magnetic field allows the laser energy to be deposited deeper within the plasma causing the expanded coating to become uniformed. We plan to show preliminary data analysis from a scaled MagLIF experiment executed on Omega to characterize and diagnose the mixing of material from the inner surface of the target preheating stage. We will show density profiles of the liner material and an assessment of possible mixing with the D2 fuel as the laser-generated x-rays and blast wave interact with the liner.
