Radial current density effects on rotating magnetic field current drive in field-reversed configurations

IC/P4-3 Simulation Studies of Field-Reversed Configurations with Rotating Magnetic Field Current Drive

First results of 3D kinetic simulations of rotating magnetic field (RMF) current drive in fieldreversed configuration (FRC) are presented. Self-consistent hybrid simulations have been performed using the HYM code for evenand odd-parity RMF and different FRC parameters. Simulations show that the RMF pushes the plasma radially inward, resulting in a reduced plasma density outside separatrix. Lowe...

On the Physics of Improved Confinement During Pulsed Poloidal Current Drive in MST Reversed-Field Pinch

Reduction of core-resonant magnetic fluctuations and improved confinement in the Madison Symmetric Torus reversed-field pinch (MST RFP) have been routinely achieved by applying the surface poloidal electric field. The created inductive poloidal electric field drives current in plasma which leads to the improved confinement. To study the effect we developed a relatively simple 1-D model in cylin...
