Density profiles of C-2W High Performance FRC
POSTER
Abstract
In TAE Technologies' current experimental device, C-2W (also called ``Norman'') [1], record breaking, advanced beam-driven field reversed configuration (FRC) plasmas are produced and sustained in steady state utilizing variable energy neutral beams, advanced divertors, end bias electrodes, and an active plasma control system. The performance of the fast ion-dominated FRC and the effects on it from beam injection and end biasing are examined using a 14-chord interferometer array in the 432.5 um far-infrared (FIR) range. Equilibrium density profiles from the array, together with other diagnostic measurements, are presented to compare early C-2W discharges and new high-performance regime plasmas. [1] H.
