C-2W’s ensemble of neutral
beams includes four static energy 15 keV H/D beams, four tunable energy 15-40 keV H/D beams, and one 40 keV diagnostic beam.

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.

Pulsed polarimetry is a LIDAR technique which uses the intensity and state of polarization of the emission to yield local measurements of density

By adjusting gas settings in each NB, this neutral flux was minimized. Localized wall heating was reduced and fast ion confinement times in the FRC plasma were improved by 25%.
