Summary:

OAK A271 DEMONSTRATION IN THE DIII-D TOKAMAK OF AN ALTERNATE BASELINE SCENARIO FOR ITER AND OTHER BURNING PLASMA EXPERIMENTS. Discharges which can satisfy the high gain goals of burning plasma experiments have been demonstrated in the DIII-D tokamak in stationary conditions with relatively low plasma current (q₉₅ > 4). A figure of merit for fusion gain Β{sub N}H₈₉/q₉₅² has been maintained at values corresponding to Q = 10 operation in a burning plasma for > 6 s or 36 τ{sub E} and 2 τ{sub R}. The key element is the relaxation of the current profile to a stationary state with q{sub min} > 1, which allows stable operation up to the no-wall ideal β limit. These plasmas maintain particle balance by active pumping rather than transient wall conditions. The reduced current lessens significantly the potential for structural damage in the event of a major disruption.
