Inference of field reversed configuration topology and dynamics during Alfvenic transients

February 2018 | Nature Communications | Paper

Active control of field reversed configuration (FRC) devices requires a method to determine the flux surface geometry and dynamic properties of the plasma during both transient and steady-state conditions.

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

October 2017 | 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.

Separatrix E×B Shear Flows and Turbulence Propagation in the C-2U FRC; Diagnostic Upgrades for Density and Magnetic Field Fluctuation Measurements in C-2W

October 2017 | APS-DPP | Poster

Ion-scale modes have been shown to be stable in the C-2/C-2FRC core, in agreement with initial gyrokinetic simulation results, with a characteristic inverted toroidal wavenumber spectrum confirmed via Doppler Backscattering (DBS) measurements.

Overview of C-2W Field-Reversed Configuration Experimental Program

October 2017 | APS-DPP | Poster

Tri Alpha Energy’s research has been devoted to producing a high temperature, stable, long-lived field-reversed configuration (FRC) plasma state by neutral-beam injection (NBI) and edge biasing/control.
