Central solenoid winding pack design for DEMO

Rainer Wesche, Pierluigi Bruzzone, Boris Stepanov, Davide Uglietti, Kamil Sedlák

The present study aims to reduce the outer radius of the central solenoid (CS) with respect to its nominal size specified by EUROfusion for a maintained CS magnetic flux. A reduced outer CS radius would allow the reduction of the overall size and cost of t ...
