Abstract
Current profile control by ac magnetic helicity injection is computationally investigated in a reversed field pinch (RFP). Three-dimensional resistive magnetohydrodynamics (MHD) computation is employed to study the nonlinear MHD. During ac helicity injection, when toroidal and poloidal surface voltages are oscillated out of phase, the parallel electric field is maintained positive over a majority of the cycle leading to current density profile flattening. The total time-averaged magnetic fluctuations are reduced and the magnetic surfaces are nonstochastic for much of the cycle. The steady-state nature of this technique could make it useful for improving RFP performance.
