Boundary modelling of the stellarator Wendelstein 7-X

Description
To justify the design of the divertor plates in W7-X the magnetic fields of finite-β HELIAS equilibria for the so-called high-mirror case have been computed for various average β-values up to left angle β right angle =0.04 with the NEMEC free-boundary equilibrium code [Hirshman (1986)] in combination with the newly developed MFBE (magnetic field solver for finite-beta equilibria) code. In a second study the unloading of the target plates by radiation was investigated. The B2 code [Braams, (1986)] was applied for the first time to stellarators to provide of a self-consistent modelling of the SOL including effects of neutrals and impurities. (orig.)
