Penetration of the Triangularity Shaping in High-beta Tokamaks and Stability of the Internal Kink Mode
Stability of the Internal n=1 kink mode in tokamak depends strongly on the ellipticity and triangularity of the plasma cross-section at q=1 surface has been investigated numerically using the equilibrium code HELENA for q-profiles close to the Bussac equilibrium and for a more realistic scenario with a flatter q-profile. The internal n=1 kink mode growth rates are computed by the ideal MHD MISHKA-1 code for the equilibrium considered. Plasma shaping optimal for the kink stability is discussed.
