Abstract

With the addition of inductive poloidal current drive for current profile control in the Madison Symmetric Torus (MST) reversed field pinch, the magnetic fluctuation amplitude halves, leading to reduced energy and particle transport. A four- to five-fold increase in the energy confinement time to tE∼5ms with both decreased Ohmic input power and increased stored thermal energy coincides with record low fluctuation amplitude and record high electron temperature ∼600eV (for MST). β[=2μo⟨p⟩/B(a)2] increases from 6% to 8%. Other improvements include reduced electrostatic edge turbulence and plasma impurity content.
