Progress on the magnetized ignition experimental platform for the National Ignition Facility

ORAL

Abstract

Magnetizing the DT fuel in an inertial confinement fusion (ICF) indirect drive (ID) target is expected to increase the ion temperature by > 0.5 keV and the neutron yield by > 50% relative to unmagnetized fuel due to reduced electron thermal conduction and alpha particle trapping. A magnetized ID project at NIF is underway and has started applying a ~ 25 T seed field to D2 gas-filled capsules in a Au:Ta high electrical resistivity hohlraum to quantify the B-field effects in these room temperature implosions and compare with modeling predictions. Ice-layered DT implosions will follow and require a new pulser design and a modified DT ice layer growth strategy. We will describe the status of the experiments and the project plan.
