Abstract

The Ergodic Magnetic Layer Experiment on ohmically heated TEXT demonstrates that a small resonant helical field (m/n = 7/2 or 7/3) with fractional amplitude b_r/B_Tof about 10^-3creates a stable ergodic magnetic layer and substantially modifies the boundary heat flow. Field line tracings accurately map the observed perturbed limiter heat load patterns. The level of the intrinsic impurities is reduced, consistent with a lower edge electron temperature, as measured by the electron cyclotron emission detector.
