Doppler Backscattering: A Powerful Plasma Turbulence and Flow Diagnostic

June 2022 | L. Schmitz | TOFE | Presentation

Microwave-based diagnostic techniques have major advantages in
high temperature/burning plasmas more robust that optical diagnostics:
– no in-vessel / first wall optical windows/mirrors needed

Turbulence Spreading and Transport Properties in the Core and Boundary of the C-2W Field-Reversed Configuration

November 2021 | L. Schmitz | APS-DPP 2021 | Poster

We investigate here the interaction of the mirror plasma scrape-off layer, characterized by drift-interchange turbulence with an exponential toroidal wavenumber spectrum, and the much more quiescent FRC core, characterized by very low ion-scale turbulence levels, and a flat or inverted toroidal wavenumber spectrum.

Identifying Density Fluctuation Modes with the FIR Interferometer System in C-2W FRCs

November 2021 | C. Deng | APS-DPP 2021 | Poster

In the TAE Technologies current experimental device, C-2W (also called “Norman”), record breaking, advanced beam-driven FRC plasmas are produced and sustained in steady state utilizing variable energy neutral beams, advanced divertors, end bias electrodes, and…
