Exploring stability of multi-layer and graded density MagLIF liners

The Magnetized Liner Inertial Fusion (MagLIF) concept compresses laser pre-heated and pre-magnetized deuterium fuel in a cylindrical liner (tube) using a pulsed power driver to achieve thermonuclear yields.[1] [2]. Recent work [3] using multi-layer, or radially graded density liners indicates that high fusion yields on future generators may be accessible at lower currents than uniform density beryllium liners. Furthermore, it is expected from previous work that grading a liner’s density profile to increase density as the radius decreases might be beneficial to maintaining liner stability, however, results can be dependent on assumptions made about material properties, such as the electrical conductivity. This talk will discuss 3D simulation results exploring stability of multi-layer and graded density liner implosions relevant to the MagLIF ICF scheme.
