C-2W Magnetic Measurement Suite

October 2017 | T. Roche | APS-DPP | Poster

Monitoring the complete magnetic evolution of the plasma is essential for understanding the system’s dynamics. Over 1000 B-field signals are monitored to provide both post-shot analysis data and data for an advanced active feedback system under development


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.


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.
