Abstract
(EN)
Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly - which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways - is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.

L'invention concerne des concepts, un système et des techniques qui fournissent un moyen pour construire des aimants supraconducteurs à champ élevé robustes à l'aide de techniques de fabrication simples et de composants modulaires qui s'étalent bien vers la commercialisation. L'ensemble aimant résultant qui utilise des bandes supraconductrices à haute température non isolées (HTS) et fournit des voies de refroidissement optimisées est structurellement robuste de manière inhérente, ce qui permet une utilisation maximale des champs magnétiques élevés disponibles avec la technologie HTS. De plus, les concepts décrits ici fournissent une commande de distributions de courant induites par trempe à l'intérieur de l'empilement de bandes et de la superstructure environnante pour dissiper en toute sécurité l'énergie de trempe, tout en obtenant simultanément un temps de charge d'aimant acceptable. Le résultat net est un ensemble aimant à champ élevé structurellement et thermiquement robuste qui est protégé passivement contre des conditions de défaillance de trempe.
