The DEMO magnet system - Status and future challenges

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Federica Demattè, Rainer Wesche, 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 ...

Co-Wound Superconducting Wire for Quench Detection in Fusion Magnets

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Nikolay Bykovskiy

High temperature superconducting (HTS) materials are widely utilized in various design proposals for fusion magnets, resulting in enhanced performance of the machines compared to the past. However, a reliable quench detection in HTS conductors remains an o ...

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 ...

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 ...

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 ...

Assessment of the Thermal-Hydraulic Performance of the European DEMO NbTi Bus Bars

Kamil Sedlák, Rainer Wesche, Roberto Guarino

We present a numerical assessment of the thermal-hydraulic performance of the NbTi bus bars designed for the European DEMO. We consider the CS, TF and PF bus bars, as well as two alternative TF options for high-current operations. The main sources of stati ...

Thermal-hydraulic analysis of alternative cable-in-conduit conductors for the European DEMO hybrid central solenoid

Kamil Sedlák, Nikolay Bykovskiy, Roberto Guarino

A hybrid design of the Central Solenoid is under study within the conceptual design phase of the European DEMO fusion reactor. It is based on HTS conductors in the innermost high-field layers, and Nb3Sn and NbTi conductors for field values below 15 T. Sinc ...
