Upgrade and Commissioning of the SULTAN Facility to Host Quench Experiments on HTS High Current Conductors

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

High Temperature Superconductors (HTS) are promising materials for future fusion magnets. One of HTS conductors' main issues is the quench protection: the quench develops much slower than in LTS, delaying the quench detection by voltage monitoring and caus ...

Design and Characterization of the Interlayer Joint Between Low-Field Nb3Sn Conductors of a Layer Wound DEMO TF Coil

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Mithlesh Kumar

In the frame of the conceptual design studies for the Toroidal Field (TF) coils of DEMO, a solution based on a layer-wound magnet, rectangular-shaped Cable-in-Conduit conductors and W&R manufacturing approach, is being developed. The feasibility and perfor ...

AC Loss Measurement of the DEMO TF React&Wind Conductor Prototype No. 2

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

The EUROfusion DEMO is being designed as the fusion machine to be built after ITER. During the preconceptual phase, several design options are investigated by theoretical analyses as well as tests on newly developed conductor prototypes. One design option ...

A new test method of AC loss assessment for fusion conductors

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

The coupling currents loss for fusion conductors is frequently assessed applying a sinusoidal field sweep of fixed, small amplitude and variable frequency. From the initial slope of the loss curve, the coupling loss time constant is derived and applied in ...
