COMBINED FRC AND MIRROR PLASMA STUDIES IN THE C-2 DEVICE

The Field Reversed Configuration (FRC) is a highbeta Compact Toroid that includes closed and open field line regions of poloidal magnetic field. Improving the transport properties of both regions is important for the overall FRC confinement and may be attempted in the C2 device. The goal of this experiment is to explore FRC sustainment by combining heating and current drive from neutral beam injection and particle fueling from a pellet injector. Additions to the C-2 device may include magnetic mirror plugs, plasma guns, and electricallybiased limiters. These additions would permit us to explore combined FRC and mirror physics, with emphasis on improving the FRC confinement.
