abstract = {Automated methods based on optimization can greatly assist
computational engineering design in many areas. In this
paper an optimization approach to the magnetic design of a
nuclear fusion reactor divertor is proposed and applied to a
tokamak edge magnetic configuration in a first feasibility
study. The approach is based on reduced models for magnetic
field and plasma edge, which are integrated with a grid
generator into one sensitivity code. The design objective
chosen here for demonstrative purposes is to spread the
divertor target heat load as much as possible over the
entire target area. Constraints on the separatrix position
are introduced to eliminate physically irrelevant magnetic
field configurations during the optimization cycle. A
gradient projection method is used to ensure stable cost
function evaluations during optimization. The concept is
applied to a configuration with typical Joint European Torus
(JET) parameters and it automatically provides plausible
configurations with reduced heat load.},
