MHD Stability Analysis of the KT-2 Tokamak Plasma

摘要

This is the final report on the project 'MHD stability analysis of the KT-2tokamak plasma'. The stability of toroidal axisymmetric divertor tokamak plasmas with up-down symmetric plasma cross-sections and KT-2 relevant plasma and device parameters has been investigated in the framework of ideal and dissipative linearized magnetohydrodynamics (MHD). Some equilibrium features that are frequently used in this report are briefly reviewed and notation agreements are made. Also, the applied definitions of some basic plasma parameters are given in order to avoid confusion. The report also contains some remarks on the numerical codes that have been used to generate the results in this report. The results of the ideal MHD stability analysis of equilibria with monotonic 1-profiles are presented. Results on dissipative MHD instabilities are also discussed. The study of 'advanced tokamak scenarios' for typical KT-2 parameters is presented.
