Experimental study of stability, quench propagation and detection methods on 15 kA sub-scale HTS fusion conductors in SULTAN

Pierluigi Bruzzone, Kamil Sedlák, Nikolay Bykovskiy, Ortensia Dicuonzo

High-temperature superconductors (HTSs) enable exclusive operating conditions for fusion magnets, boosting their performance up to 20 T generated magnetic fields in the temperature range from 4 K to 20 K. One of the main technological issues of HTS conduct ...

Quench experiments on sub-size HTS Cable-In-Conduit Conductors for fusion applications: Data analysis and model validation

Pierluigi Bruzzone, Boris Stepanov, Kamil Sedlák, 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 ...

Preliminary Design of a High Current R&W TF Coil Conductor for the EU DEMO

Pierluigi Bruzzone, Kamil Sedlák, Federica Demattè

Paschen failures in ITER, W7-X and JT60 superconducting coils at the acceptance tests have shown that it is highly desirable to lower the coil discharge voltage (U-d) of the DEMO Toroidal Field (TF) coils. Another benefit of lowering the U-d might be the r ...

Measurements of AC Loss Evolution in ITER TF Conductors

Pierluigi Bruzzone, Kamil Sedlák

AC loss in the Nb3Sn cable-in-conduit conductors (CICC) usually decreases after the conductor undergoes electromagnetic cycling. This can be attributed to the increase of inter-strand resistance due to the detachment of the strand-bonding during cyclic loa ...

Diffusion-Bonding Between Strands and Modeling of Splices of Nb3Sn Rutherford Cables

Pierluigi Bruzzone, Kamil Sedlák, Nikolay Bykovskiy

Particle accelerators foresee the use of Nb3Sn in the next generation of dipole magnets. A common design strategy is to grade the coil, i.e., to optimize the quantity of superconductor in the turns with respect to the magnetic field intensity. As a consequ ...

Application of Copper Thermal Spraying for Electrical Joints between Superconducting Nb3Sn Cables

Pierluigi Bruzzone, Vincenzo D'Auria

This manuscript reports on the application of copper thermal spraying in the manufacturing process of an electrical connection between Nb3Sn cables for superconducting magnets of fusion reactors. The joint is realized through diffusion bonding of the spray ...

The DEMO magnet system - Status and future challenges

Pierluigi Bruzzone, Rainer Wesche, Kamil Sedlák, Davide Uglietti, Federica Demattè, Roberto Guarino, Mithlesh Kumar, Vincenzo D'Auria, Ortensia Dicuonzo, Chiara Frittitta

We present the pre-concept design of the European DEMO Magnet System, which has successfully passed the DEMO plant-level gate review in 2020. The main design input parameters originate from the so-called DEMO 2018 baseline, which was produced using the PRO ...

Parametric study of the TF coil design for the European DEMO

Pierluigi Bruzzone, Kamil Sedlák, Rainer Wesche, Roberto Guarino

In addition to a reduced number of feeders, which would simplify their integration in the cryostat of the tokamak, the present study considers the possibility to reduce the voltage during safety discharge of the toroidal field (TF) coils. A lowered dischar ...
