MHD stability of ITER equilibriaFunded under: EAEC-FUSION 12C
The present report summarises numerical MHD stability studies undertaken by European groups during 1994 within the framework of the ITER task MHD Stability of ITER Profiles and Equilibria. The studies mainly concern a set of ITER equilibria supplied by the ITER Joint Central Team. These equilibria were generated by transport calculations with the PRETOR code using the Rebut-Lallia-Watkins transport model and two-dimensional calculations with the TEQ code (LLNL). The equilibria have been tested for stability to ideal and resistive MHD modes and the results are summarised in Sections 2 and 3. Section 4 reports a study of the stability of ITER equilibria with central q below unity, using ideal MHD and, for comparison, ideal drift kinetic theory to account for the thermal trapped particles. Section 5 gives a brief summary of stability studies of advanced tokamak equilibria, both with respect to internal modes and the possibility of stabilising low-n modes by resistive walls and plasma rotation.
