Electromagnetic fluctuation properties in C-2W Field-Reversed Configuration (FRC) deuterium and mixed D/H plasmas

October 2024 | L. Schmitz | APS DPP 2024 | Poster

TAE’s C-2W FRC shows key differences in fluctuation properties between hydrogen and deuterium plasmas, with increased magnetic fluctuations in FRC and low ion-scale fluctuations in the core. These findings, consistent with simulations, inform the design of diagnostics for the upcoming Copernicus device.

Magnetic Mode Decomposition using Sparse Regression of an Irregular Mirnov Array in C-2W

A workhorse diagnostic for investigating magnetic fluctuations in C-2W is a
Mirnov probe array comprising 3-axis magnetic probes for sensing “B-dot”
fluctuations at the CV wall arranged in evenly spaced rings.
