Fast-framing camera based observations of spheromak-like plasmoid collision and merging process using two magnetized coaxial plasma gun

April 2018 | T. Matsumoto | HTPD2018 | Poster

We have been conducting compact toroid (CT) collision and merging experiments by using two magnetized
coaxial plasma guns (MCPG). As is well known, an actual CT/plasmoid moves macroscopically in a confining magnetic field. Therefore, three-dimensional measurements are important in understanding the behavior of the CTs.

Simulations of High Harmonic Fast Wave Heating on the C-2U Advanced Beam-Driven Field-Reversed Configuration Device

October 2017 | X. Yang | EPJ Web Conference | Paper

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.

Multi-Wavelength Interferometry and Axial Polarimetry on C-2W

October 2017 | Roger J Smith | APS-DPP | Poster

Tri Alpha Energy’s C-2W device is operational and represents another major step in a progression of advanced beam-driven Field-Reversed Configuration (FRC) confinement devices that have prolonged the lifetime, increased stability and added significant neutral beam injection power to heat and sustain an FRC plasma.
