Generation of the Resonant Magnetic Fields in the T-15MD Tokamak

Abstract

Requirements for generation of the resonant magnetic fields in tokamaks for controlling magnetohydrodynamic (MHD) plasma perturbations, stabilizing edge localized modes (ELM), and suppressing accelerated electron beams are considered. A preliminary design of a system for generating external resonant magnetic fields on the T-15MD tokamak is considered. The design is based on a system of 48 multipole coils located inside a vacuum vessel (16 windings around the equatorial plane, 16 windings in the upper cone, and 16 windings in the lower cone) to create resonant magnetic fields with poloidal and toroidal harmonics m = 1–8, n = 1–4.
