Abstract

The interactions between the plasma and the radio frequency circuit in rotating
magnetic field (RMF) current drive experiments are investigated numerically.
A simplified 1D model for slowly varying conditions is used to study the
penetration of the RMF into the plasma. The RMF is assumed to be generated
using a two-phase two-coil arrangement and the effect of the spatial harmonics
of the field is included up to the ninth harmonic. Both the coil inductance
and resistance vary as the RMF penetrates into the plasma and thus influence
the current in the antenna coils. The simulation results help in understanding
the complex interactions between the radio frequency circuit and the plasma
discharge and may help in optimizing the performance of RMF current drive
experiments.
