(2000)] and initial theoretical analyses, the Centrifugal Mirror concept is being further explored by the construction
of the Centrifugal Mirror Fusion Experiment (CMFX) [C. A. Romero-Talamas, this conference] at the University of
Maryland. This prompts a deeper inquiry into the underlying confinement and stability properties of centrifugal
mirrors as a class of devices. Here we present a model, calculated in the rapidly-rotating well-confined limit, which
can be used for the rapid prototyping of such devices.
In this limit, we present kinetic equilibrium calculations incorporating the effect of finite Alfven Mach number.
This magnetic equilibrium is used to compute approximate end loss rates and electrical properties of the plasma.
Corrections to the parallel electric field are computed to ensure all losses are ambipolar. This provides a self-consisent
basis for a 0D “systems” model of a centrifugal mirror machine. As examples we provide design points corresponding
to CMFX and an upgraded device capable of achieving breakeven.
