Title (EN) CURRENT LEAD FOR CRYOGENIC APPARATUS
(FR) FIL CONDUCTEUR DE COURANT POUR APPAREIL CRYOGÉNIQUE
Abstract:
(EN) In embodiments of the invention, a superconductor lead is configured to have less ohmic heating by its own current and less heat conduction from room temperature to cryogenic temperature, where a cryogenic apparatus is located. The superconducting lead with no ohmic resistance and low thermal conductivity disclosed herein maximizes current capacity by placing superconductors in parallel, each having equal current. Thus, the resistances are controlled to provide uniform current distribution through each superconductor of the high temperature superconducting (HTS) lead.
(FR) Dans des modes de réalisation de l'invention, un fil supraconducteur est conçu de façon à présenter un chauffage ohmique moindre par son propre courant et une conduction thermique moindre de la température ambiante jusqu'à une température cryogénique, à laquelle se trouve un appareil cryogénique. Ledit fil supraconducteur ne présentant aucune résistance ohmique et présentant une faible conductivité thermique de la présente invention maximise la capacité du courant en plaçant des supraconducteurs en parallèle, chacun de ceux-ci recevant le même courant. Ainsi, les résistances sont commandées pour fournir une répartition uniforme du courant à travers chaque supraconducteur du fil supraconducteur à haute température (HTS).
