  Presented is a semi-analytic model of magnetized liner inertial fusion
(MagLIF). This model accounts for several key aspects of MagLIF, including: (1)
preheat of the fuel (optionally via laser absorption); (2) pulsed-power-driven
liner implosion; (3) liner compressibility with an analytic equation of state,
artificial viscosity, internal magnetic pressure, and ohmic heating; (4)
adiabatic compression and heating of the fuel; (5) radiative losses and fuel
opacity; (6) magnetic flux compression with Nernst thermoelectric losses; (7)
magnetized electron and ion thermal conduction losses; (8) end losses; (9)
enhanced losses due to prescribed dopant concentrations and contaminant mix;
(10) deuterium-deuterium and deuterium-tritium primary fusion reactions for
arbitrary deuterium to tritium fuel ratios; and (11) magnetized alpha-particle
fuel heating. We show that this simplified model, with its transparent and
accessible physics, can be used to reproduce the general 1D behavior presented
throughout the original MagLIF paper [S. A. Slutz et al., Phys. Plasmas 17,
056303 (2010)]. We also discuss some important physics insights gained as a
result of developing this model, such as the dependence of radiative loss rates
on the radial fraction of the fuel that is preheated.
