Numerical Analysis of Non-Insulated DEMO TF Coils

Pierluigi Bruzzone, Kamil Sedlák, Nikolay Bykovskiy

The design of small solenoids without/with-partial insulation (PI) among turns or layers has been proven to grant higher thermal stability than for standard insulated cases. This technology also implies higher safety standards, by e.g. reducing the coil vo ...

Bending Tolerance of React&Wind Nb3Sn Conductors for Fusion Magnets

Pierluigi Bruzzone, Kamil Sedlák, Federica Demattè, Chiara Frittitta

The react-and-wind technique for manufacturing of large Nb3Sn fusion magnets (RW) is very attractive because of the superior performance of the Nb3Sn with lower thermal strain compared to the wind-and-react technique. The procedure for magnet winding is al ...
