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 | L. Schmitz | 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 | H. Gota | 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.

High Time Resolution Reconstruction of Electron Temperature Profiles with a Neural Network in C-2U

October 2017 | Gabriel Player | APS-DPP | Poster

An attempt to experimentally determine electron heating due to neutral beam injection highlighted a diagnostic gap – lack of time resolution on single-shot Thomson measurements.
