COMPARISON OF MHD STABILITY RESULTS OBTAINED WITH THE BETA 3-D AND HERA 2D CODES
Comparison of MHD stability results obtained for helically symmetric equilibria with two codes, HERA and BETA, showed excellent agreement in growth rates and marginal stability parameters. While HERA is the helical version of the ERATO linearized 2D stability mode, BETA obtains non-linear 3D equilibria and their (nonlinear) stability properties. The cases studied comprise internal, i.e., fixed plasma boundary, resonant and non-resonant modes in low shear equilibria with intermediate and small beta values.
