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.

Development of Spatial Heterodyne Spectroscopy Measurements for the C-2W Plasma Expansion Divertor
