High Time Resolution Reconstruction of Electron Temperature Profiles with a Neural Network in C-2U

October 2017 | Gabriel Player | APS-DPP | Poster

An attempt to experimentally determine electron heating due to neutral beam injection highlighted a diagnostic gap – lack of time resolution on single-shot Thomson measurements.


Development of Spatial Heterodyne Spectroscopy Measurements for the C-2W Plasma Expansion Divertor

October 2017 | D. Sheftman | APS-DPP | Poster

Accurate operation and high performance of the open field line plasma surrounding the Field Reversed Configuration (FRC) is crucial to achieving the goals of successful temperature ramp up and confinement improvement on C-2W.


Compact Toroid Injection Fueling in a Large Field-Reversed Configuration

May 2017 | T. Asai | Nuclear Fusion | Paper

A repetitively driven compact toroid (CT) injector has been developed for the large eld- reversed con guration (FRC) facility of the C-2/C-2U, primarily for particle refueling. A CT is formed and injected by a magnetized coaxial plasma gun (MCPG) exclusively developed for the C-2/C-2U FRC.
