On the computation of tokamak equilibria with negative core toroidal current
Published online by Cambridge University Press: 20 December 2006
Abstract
A numerical scheme is presented which is able to solve the Grad–Shafranov (GS) equation in tokamak plasmas with toroidal current reversal for input profiles that are not restricted to any particularly chosen models. Its flexibility is subsequently tested, computing a GS equilibrium with off-axis negative toroidal current density strong enough to generate two nested current-reversal surfaces.
