Upgraded Diagnostic Array for End Losses from C-2W’s Open Field Line Plasma

November 2021 | M. Griswold | APS-DPP 2021 | Poster

An upgraded array of energy analyzers and bolometers has been installed in the divertors of C-2W to measure axial power losses as well as the electron temperature and ion energy distribution function (IEDF) of the plasma at the termination point of the open field lines. relatively large Larmor radius.

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.
