Numerous efforts have been made at Tri-Alpha Energy (TAE) to theoretically explore the physics of microwave electron heating in field-reversed configuration (FRC) plasmas. For the fixed 2D profiles of plasma density and temperature for both electrons and thermal ions and equilibrium field of the C-2U machine, simulations with GENRAY-C ray-tracing code have been conducted for the ratios of / ci[D] in the range of 6 – 20.

The Tri Alpha Energy (TAE) code RF-Pisa is a Finite Larmor Radius (FLR) full wave code developed through the years to study RF heating in the Field Reversed Configuration (FRC) in both the ion and electron cyclotron regimes.

Gyrokinetic simulations of C-2-like field-reversed configuration (FRC) find that electrostatic drift- waves are locally stable in the core. The stabilization mechanisms include finite Larmor radius effects, magnetic well (negative grad-B), and fast electron short circuit effects.

The rotating magnetic field-driven field-reversed configuration (FRC), such as Rotamak or PFRC experiment, was recently proposed as a test bench at TAE Technologies to experimentally pioneer the study of microwave electron heating.

Norman Rostoker pioneered research of (1) plasma-driven accelerators and (2) beam-driven fusion reactors. The collective acceleration, coined by Veksler, advocates to drive above-ionization plasma waves by an electron beam to accelerate ions. The research on this, among others, by the Rostoker group incubated the idea that eventually led to the birth of the laser wakefield acceleration (LWFA), by which a large and robust accelerating collective fields may be generated in plasma in which plasma remains robust and undisrupted.

Different microwave heating scenarios for the C-2 plasmas have been investigated recently with use of both the Genray ray-racing code and the IPF-FDMC full-wave code, and the study was focused on the excitation of the electron Bernstein wave (EBW) with O-mode launch.
