Title: Calculation of stellarator equilibria in vacuum flux surface coordinates

Technical Report ·
DOI:https://doi.org/10.2172/6440725· OSTI ID:6440725

Details are given of a three-dimensional stellarator equilibrium code NEAR. This code uses a set of vacuum flux coordinates as an Eulerian basis for the equilibrium calculations. This coordinate system provides an economic representation of the complex geometry associated with stellarators. The equilibrium equations are solved by an energy minimization technique employing a conjugate gradient iteration scheme. The results of extensive numerical convergence studies are presented. Also comparisons with existing codes are made to benchmark the NEAR code.
