Helion's Trenta prototype compressed Field Reversed Configuration
(FRC) plasmas to thermonuclear fusion conditions, reaching 9 keV
plasma temperatures [1].  FRC plasmas are fundamentally high-beta and
if heated through pulsed, adiabatic compression, they operate in a
unique collisionality regime that supports both thermonuclear fusion
conditions as well as maintains an ion to electron temperature ratio.

In the presented work, a theoretical analysis of FRC compression to
generator-relevant fusion conditions is derived from fundamental
scaling laws. This work includes independent ion and electron heating
[2], radiation losses [3], empirical particle transport scaling [4],
fusion reaction rates, ion temperature distribution evolution, and D,
T, and He-3 fuels.

As will be shown, for all operating conditions above 20 keV, a
high-beta D-He-3 FRC outperforms a low-Beta D-T plasma in terms of
electrical and fusion power output.
