Talk Title: "Pulsed-Power-Driven Magneto-Inertial Fusion Research on the Z Facility"

Abstract:

The Z facility at Sandia National Laboratories consists of the world’s largest pulsed power driver and a multi-kilojoule, terawatt laser.  The mission of the Z Facility includes investigating material properties under extreme conditions, high power x-ray sources, and inertial confinement fusion (ICF).  Of the three major approaches to ICF currently being pursued in the U.S., the Z Facility is uniquely suited to investigate the efficacy of magnetic direct drive ICF.

Magnetic direct drive concepts typically operate on longer time scales than traditional ICF to efficiently match to the pulsed-power driver, so they require some help to achieve the conditions necessary for fusion.  In magneto-inertial fusion, a magnetic field is used improve performance of an ICF concept by reducing thermal conduction losses.  Sandia’s Magnetized Liner Inertial Fusion (MagLIF) concept uses a laser to pre-heat an axially-magnetized fuel volume just prior to the implosion, which allows the fuel to reach several keV temperatures at stagnation.  Not only does this axial magnetic field inhibit thermal conduction in the radial direction, but it also helps trap charged-particle fusion products at stagnation, which is necessary for self-heating in high yield ICF designs.
