Description
Gross-energy-confinement times (tau/sub E/) in the ISX-A (Impurity Study Experiment) tokamak exceeded predictions of the usual empirical scaling relations. We attribute this performance to reductions of impurity radiation and magnetohydrodynamically driven loss channels. The value of tau/sub E/ reached a limit as a function of plasma density. We suggest that this limit is due to a transition from electron- to ion-dominated loss regimes. Maximum attainable values of tau/sub E/ increased with discharge current, in agreement with this interpretation
