Abstract

A control matrix MHD (magnetohydrodynamic) equilibrium code, BEQ, and the Tokamak Simulation Code (TSC) are used to compute programmed double-null (DN) divertor sweep trajectories that maximize sweep distance while simultaneously satisfying a set of strict constraints: minimum lengths of the field lines between the X-point and strike points, minimum spacing between the inboard plasma edge and the limiter, maximum spacing between the outboard plasma edge and the ICRF (ion cyclotron range of frequencies) antennas, minimum safety factor, and linked poloidal flux. A sequence of DN diverted equilibria and a consistent TSC fiducial discharge simulation are used in evaluating the performance of the BPX (Burning Plasma Experiment) divertor shape and possible modifications
