PLASMA BOUNDARY EXPERIMENTS ON DIII-D TOKAMAK

[摘要] A survey of the boundary physics research on the DIII-D tokamak and an outline of the DIII-D Advanced Divertor Program (ADP) is presented. We will present results of experiments on impurity control, impurity transport, neutral particle transport, and particle effects on core confinement over a wide range of plasma parameters, I(p) less-than-or-equal-to 3 MA, beta-T less-than-or-equal-to 10.7%, P(auxiliary) less-than-or-equal-to 20 MW. Based on the understanding gained in these studies, we in collaboration with a number of other laboratories have devised a series of experiments (ADP) to modify the core plasma conditions through changes in the edge electric field, neutral recycling, and plasma-surface interactions.
