Electron cyclotron assisted startup and heating scenarios in the Compact Ignition Tokamak (CIT).

摘要

The Compact Ignition Tokamak (CIT) operating scenario calls for ramping the toroidal magnetic field from B(sub T) = 8.0 to 10.0 Tesla in a few seconds, followed by a burn cycle and a ramp-down cycle. Simultaneously, the plasma must be heated from an initial low beta equilibrium ((bar (beta)) (approx equal) 0.44% at 7.0 to 8.0 Tesla) to a final burn equilibrium ((bar (beta)) = 2.5--5.5%) having 10.0 Tesla on the magnetic axis. This paper proposes ECRF heating of CIT to ignition utilizing a constant source frequency but with a time dependent, variable angle of injection. 10 refs., 3 figs.
