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 ...

High-Current Low-Voltage Power Supply for Superconducting Magnets

Émilien Luc Henri Coulinge

In the wide range of applications for power supplies, the ones dedicated to feeding superconducting magnets occupy a niche. This particular kind of magnets has the intrinsic property of having zero resistance, and is only used in high-end facilities for fu ...

To the Optimization of Quench Performance for a Large REBCO Cable-in-Conduit Conductor

Davide Uglietti

REBCO cable-in-conduit conductors at the level of tens of kiloamperes are being developed for application in fusion magnets. One important aspect to study is their performance in the case of a quench event. A conductor should survive from such an event wit ...
