S.Korepanov for TAE team
A high temperature, stable, long-lived field-reversed configuration (FRC) plasma state has been produced in the C-2U device at Tri Alpha Energy. C-2U is the next generation of C-2 device [1-3]. The tangential co-current neutral beam injection power is increased from 4 MW to 10+MW. A new edge plasma rotation control system based on biased plasma generator is used to improve plasma stability. The inner surface of the wall has Ti-coating. That reduces background neutral gas density and increases lifetime of the fast ions. C-2U experiments have demonstrated a sustainment of advanced beam-driven FRC plasma state for up to 5 ms. The overall C-2U experimental program and recent accomplishments will be reviewed.
