A simple and fast method to calculate the coil currents and the external poloidal flux and magnetic field for fixed boundary equilibria
Abstract A simple and fast method to calculate the coil currents and the exter-
nal poloidal flux and magnetic field consistent with a given internal MHD
equilibrium and coil geometry is presented. The constrained optimization
technique employed allows to fix the exact position of the X-points. The ex-
ternal poloidal flux and fi eld are calculated using Green's functions expressed
in terms of elliptic integrals that are calculated using a fast and accurate rou-
tine. The calculation can be limited to the region between the plasma and
the device wall. An example for a double null con guration is presented.
