Transport reduction by current profile control in the reversed-field pinch
An auxiliary poloidal inductive electric field applied to a reversed-field pinch (RFP) plasma reduces the current density gradient, slows the growth of m = 1 tearing fluctuations, suppresses their associated sawteeth, and doubles the energy confinement time. This experiment attacks the dominant RFP plasma loss mechanism of parallel streaming in a stochastic magnetic field. The auxiliary electri...
متن کاملNumerical studies of active current profile control in the reversed-field pinch
Quenching of the reversed-field pinch (RFP) dynamo is observed in numerical simulations using current profile control. A novel algorithm employing active feedback of the dynamo field has been utilized. The quasi-steady state achieved represents an important improvement as compared with earlier numerical work and may indicate a direction for the design of future experiments. Both earlier and the...

15 صفحه اولCurrent profile control by alternating current magnetic helicity injection
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 majori...
متن کاملMeasurement of the current-density profile and plasma dynamics in the reversed-field pinch.
First measurements of the current-density profile in the core of a high-temperature reversed-field pinch are presented. The current-density profile is observed to peak during the sawtooth cycle and broaden promptly at the crash. This change in profile can be linked to magnetic relaxation and the dynamo which is predicted to drive antiparallel current in the plasma core. For high-confinement dis...
