论文摘要
由高级导体技术制造的圆形芯（CORC）电缆的导体，当前密度超过300 AMM^-2在4.2 K时，弯曲直径高达3.5 cm，被认为是下一代高场电源应用和磁铁的最强候选者之一。在本文中，我们为他们的单层和双层Corc电缆提供了一个完整的3D FEM模型，该电缆分别由多达三个和六个超导胶带组成，披露了在60吨以上的磁场上的AC损耗的完整AC损耗曲线，以及两种设计中电流密度的实际分布，以及两种设计中电流层的实际分布。该模型基于所谓的H构型，使磁带的真实三维性在不经常发生到2D薄膜方法的情况下，这些方法不遵循未遵循著名bean型模型的非物理表面电流出现。同样，已经获得了与单层和双层电缆的实验测量的AC-alses的良好一致，并在本文中披露了该模型的所有细节。
The Conductor on Rounded Core (CORC) cables manufactured by Advanced Conductor Technologies with current densities beyond 300 Amm^-2 at 4.2 K, and bending diameter of up to 3.5 cm, are considered as one of the strongest candidates for the next generation of high field power applications and magnets. In this paper, we present a full 3D FEM model for their monolayer and bilayer CORC cables made with up to three and six superconducting tapes respectively, disclosing the full curve of AC losses for the monolayer cable at magnetic fields beyond 60 mT, and the actual distribution of current density along and across the thickness of the superconducting tapes in both designs. The model is based on the so-called H-formulation, allowing to incorporate the true three-dimensionality of the tapes without recurring to 2D thin-film approaches where non-physical surface currents that do not follow the celebrated Bean's model for type-II superconductors appear. Likewise, good agreement with the experimentally measured AC-losses for the monolayer and bilayer cable have been obtained, with all the details of the model disclosed in this paper.
