Global stability of plasmas with helical boundary deformation and net toroidal current against n = 1,2 external modes
In this paper we resume a numerical study of the global stability of plasmas with helical boundary deformation and non null net toroidal current. The aim was to see whether external modes with n = 1,2 (n toroidal mode number) can be stabilized at values of beta inaccessible to the tokamak. L=2,3 configurations with several aspect ratios and different numbers of equilibrium field periods are considered. A large variety of toroidal current densities and different pressure profiles are taken into account. Mercier stability is also investigated.
