Multipole divertor

Existing tokamak fusion reactor designs with magnetic divertors have therefore exclusively poloidal field or multipole divertors. But using versions with multipoles installed inside, as in ASDEX, it has not yet been possible to find a feasible solution compatible with reactor access, manufacture and service requirements. 

Poloidal field divertors with external multipoles would appreciably simplify access and manufacture, but greatly increase operating and manufacturing costs. We shall return to this point later. Poloidal field divertors will also have a problem with the load capacity of the collectors. 

The technical problems of the poloidal field system depend on the configuration concept of the equilibrium field coils and the multipole divertor winding. A basic distinction is made between two types of configuration ...
