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