The Princeton spectral equilibrium code: PSEC
A fast computer code has been developed to calculate free-boundary solutions to the plasma equilibrium equation that are consistent with the currents in external coils and conductors. The free-boundary formulation is based on the minimization of a mean-square error \(\epsilon\) while the fixed-boundary solution is based on a variational principle and spectral representation of the coordinates x(\(\psi\),\(\theta)\) and z(\(\psi\),\(\theta)\). Specific calculations using the Columbia University Torus II, the poloidal divertor experiment (PDX), and the tokamak fusion test reactor (TFTR) geometries are performed.
