TL;DR: The C-2W experimental device (also called "Norman") as discussed by the authors is the world's largest compact-toroid (CT) device, which has several key upgrades from the preceding C2U device such as higher input power and longer pulse duration of the NBI system as well as installation of inner divertors with upgraded electrode biasing systems.

TL;DR: Gota et al. as discussed by the authors determined the time-dependent geometry, including high-frequency oscillations, of the plasma density in TAE's C-2W experiment as a joint Bayesian reconstruction from a 14-chord FIR interferometer in the midplane, 32 Mirnov probes at the periphery, and 8 shine-through detectors at the targets of the neutral beams.

A combined millimeter wave and CO 2 interferometer on the C-2W Jet plasma
Roger Smith,Tae Team +1 more
TL;DR: A two wavelength tangentially viewing multi-chord interferometer has been built for the Jet plasma of the C-2W experiment and will play a pivotal role in assessing the FRC before merging and the operation of the inner and outer divertors and particle outflow.
