Supercoil: A Model for the Computational Design of Tokamaks

Abstract SUPERCOIL is a code for the computational design of tokamaks, including in particular ignited next-generation devices. It takes into account all physical, technical and geometrical constraints relevant to the basic design of a tokamak. Among the solutions of the model equations that meet all constraints the one optimized with respect to a prescribed figure of merit (typically capital cost) is determined. The main components modelled are the plasma, blanket and shield, the TF system and the PF system. The main characteristics of the component models are summarized and a detailed description of the solution method is given. A typical NET study point is given as an illustrative example. The validity of the code is assessed by applying it to the ASDEX Upgrade tokamak.
