Coupled transport in field-reversed configurations

February 2018 | Physics of Plasmas | Paper

Coupled transport is the close interconnection between the cross-field and parallel fluxes in differ- ent regions due to topological changes in the magnetic field. This occurs because perpendicular transport is necessary for particles or energy to leave closed field-line regions, while parallel transport strongly affects evolution of open field-line regions.

Spectral and Intensity Calibration of a Thomson Scattering Diagnostic for the C-2W Field- Reversed Configuration Plasma Experiment

April 2018 | HTPD2018 | Poster

The C-2W Thomson Scattering diagnostic consists of two individual systems for monitoring electron temperature and density; one system in the central region is operational and the second system, currently under design, will monitor the open field line jet region1.

Magnetic Diagnostic Suite of the C-2W Field-Reversed Configuration Experiment

April 2018 | HTPD2018 | Poster

The C-2W machine is the world’s premier Advanced Beam-Driven FRC
n Monitoring the complete magnetic evolution of the plasma is essential for
understanding the system’s dynamics
n Over 500 B-field signals are monitored to provide both post-shot analysis data and data for an advanced active feedback system.

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

April 2018 | 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 | 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.
