Abstract

Current profile control has been employed in the Madison Symmetric Torus reversed field pinch to reduce the magnetic fluctuations responsible for anomalous transport. An inductive poloidal electric-field pulse has been applied to flatten the parallel current profile, thus reducing the dynamo fluctuation amplitude required to sustain equilibrium. This technique demonstrated a substantial reduction in fluctuation amplitude and improvement in energy confinement. Particle confinement improved and plasma impurity contamination has been reduced.
