In case of mixed constitutive properties, in inductive-conductive or in capacitive-conductive multipoles, the impedance is a combination of two paths, one per nature of system constitutive properties. This fusion of purely inductive or capacitive paths with a purely conductive one justifies the adoption of common mounting rules for all natures of dipoles. 

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. 

Resume POLOIDAL FIELD SYSTEM FOR COMMERCIAL FUSION REACTORS WITH MULTIPOLE DIVERTOR COILS ARE NOT YET FEASIBLE. 

Eq. (48) then requires W /Wg = 1. The radiation is not reduced at all if B is increased in a multipole-surmac to keep the diffusion losses the same. The only advantage of a surmac lies in the better filling factor, which gives a higher fusion power. If Bohm diffusion is assumed, the situation is even worse one obtains W /Wg = R3/2d3 >> 1. Okuda—Dawson scaling is independent of B. In this case the loss rates are equal only if R/d = v, in which case...

To evaluate fusion fuel cycles from D-D to p-B, accurate measurements of many cross sections are needed. The most complete compilation to date was made by a panel of experts assembled by TRW, Inc. and EPRI. For multipole-surmacs these primary reactions producing few neutrons are of greatest interest ...
