Abstract

Through time dependent transport simulation, we have developed an operation scenario with high bootstrap, negative shear configuration for KT-2 tokamak, so that investigations of the so-called “advanced tokamak operations” are possible. In this study, we have concentrated on calculation of power requirements of heating and current drive system, MHD (Magnetohydrodynamic) stability and compatibility with PF (Poloidal Field) coil system. The study shows that high bootstrap (>70%), MHD stable (up to β_N⩽3.9) operation scenario with negative shear configuration is possible within KT-2 tokamak design specification
