Quench experiments on sub-size HTS Cable-In-Conduit Conductors for fusion applications: Data analysis and model validation
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Ortensia Dicuonzo
The recent experimental campaign, carried out in the upgraded SULTAN facility and supported by EUROfusion, investigated quench propagation in high field, sub-size HTS Cable-In-Conduit Conductors. The available experimental data consist of voltage, jacket a ...
ELSEVIER SCI LTD2023Upgrade 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 ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Design 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 ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021A New Cabled Stabilizer for the Nb3Sn React&Wind DEMO Conductor Prototype
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Mithlesh Kumar, Vincenzo D'Auria
A Nb3Sn based, React&Wind flat cable, named RW2, was developed in the past three years at the Swiss Plasma Center in the scope of the EUROfusion conceptual studies for DEMO. The test results presented earlier proved an excellent DC performance, but large e ...
2021T-cs degradation of ITER TF samples due to fast current discharges
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov
Direct current tests performed in the past on the conductor samples of the toroidal field (TF) ITER coils revealed degradation of current sharing temperature, T-cs. The degradation progresses with repetitive electromagnetic loading, and also with thermal c ...

IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Advance in the conceptual design of the European DEMO magnet system
Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Boris Stepanov, Rainer Wesche, Roberto Guarino, Mithlesh Kumar, Vincenzo D'Auria, Ortensia Dicuonzo, Chiara Frittitta, Elena Gaio, Alberto Ferro
The European DEMO, i.e. the demonstration fusion power plant designed in the framework of the Roadmap to Fusion Electricity by the EUROfusion Consortium, is approaching the end of the pre-conceptual design phase, to be accomplished with a Gate Review in 20 ...
IOP PUBLISHING LTD2020Inter-Layer Joint of Nb3Sn React&Wind Cables for Fusion Magnets
Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Vincenzo D'Auria
The Swiss Plasma Center (SPC) has developed a layout of Toroidal Field (TF) coil for EUROfusion DEMO tokamak, based on the reference tokamak baseline of 2015. Each TF coil winding pack is wound with graded Nb3Sn conductors and consists of 12 single layers, ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020AC 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 ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020A 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 ...
