The maximum experimental volume averaged toroidal beta in DIII-D scales with the plasma current divided by the plasma minor radius and the toroidal field, βT ∝ I/aB. βT = 11% has been achieved at high normalized current by operating at high plasma elongation. κ = 2.3, and high triangularity, δ = 0.8, near the axisymmetric stability limit. In a limited range of I/aB, βT (%) = 5I/aB (MA/m/T) has been obtained. Stability calculations indicate that the high beta stability limit depends on the profiles of the current density and the pressure.
