Abstract
Using newly developed techniques and improved diagnostics, rotating wall-st abilized discharges have been maintained in the DIII-D tokamak for 30 chara cteristic resistive wall decay times-significantly longer than was previous ly achieved. The terminating resistive wall mode has been directly identifi ed using internal fluctuation diagnostics, and its correlation with the slo wdown in the plasma rotation is established.
