INVESTIGATION OF HIGH-BETA TOKAMAK STABILITY WITH THE PROGRAM HBT
The numerical programme HBT has been employed to study global and local stability of high beta axisymmetric toroidal plasmas with various cross-sections. The stability results of different classes of equilibria for a circular plasma show that high stable betas: <beta>/epsilon = .113 can be found when negative toroidal current densities are admitted in a small region on the inside of the torus. Shaping the cross-section makes further improvements possible. The optimum betas found are in qualitative agreement with Troyon's scaling law.
