Exploring the parameter space of MagLIF implosions using similarity scaling. II. Current scaling

Magnetized liner inertial fusion (MagLIF) is a magneto-inertial-fusion (MIF) concept, which presently being studied on the Z pulsed power facility. The MagLIF platform has achieved interesting plasma conditions at stagnation and produced significant yields in laboratory. Given relative success of MagLIF, there strong interest to scale higher peak currents. However, scaling not entirely straightforward due large dimensionality experimental input parameter space numerous physical processes involved MIF implosions. In this work, we propose novel method loads Our based similarity (or similitude) attempts preserve much physics regimes already known or today's pulsed-power driver. By avoiding deviations into unexplored and/or less well-understood regimes, risk unexpected outcomes future scaled-up experiments reduced. Using arguments scaling, derive rules for parameters characterizing load (as functions characteristic current driving implosion). We then test estimated laws various metrics measuring performance against results 2D radiation–magneto-hydrodynamic hydra simulations. Agreement found between theory simulation results.
