Description
Without current drive (CD) Field-Reversed-Configuration (FRC) disappears at skin time. Experiments in C-2U in Tri Alpha Energy strongly indicate that FRC survives much longer than skin time and thus suggest that some form of CD exists. In this presentation we are considering conditions under which FRC configuration can be maintained or even expanded. FRC as well as high-β open traps have a notorious property of interconnecting of all major processes: equilibrium, plasma rotation, diffusion, and CD. We are building simple self-consistent description of these processes which includes both collision and turbulent-driven effects. We are applying this description to situation close to experimental and finding conditions under which CD can exist in FRC without violating other experimental observations. We are also considering such key issues as the possibility transforming open-trap configuration into FRC in the beam-driven plasma.
