Several new conductor designs for fusion applications, based on high temperature superconducting (HTS) materials, have been recently proposed worldwide. Most of them are based on the twisted-stacked-tape cable (TSTC) idea: a stack of HTS tapes is twisted, soldered and embedded in a copper tube, constituting what we identify here as a ‘strand’. Few strands are then twisted around a central core to make an HTS cable. The cable is finally inserted in a stainless-steel jacket, which provides mechanical support and confinement for the forced flow of the supercritical helium coolant through the interstitials among the strands. The thermal gradients that build up in a TSTC make the 1D thermal-hydraulic models developed for low temperature superconducting magnets unsuitable to study fast transients such as quench propagation. A new model is presented here, which allows describing each strand, and separately accounting for the respective superconducting (SC) stack and coppe...

基于双绞叠带式电缆概念的高温超导导管内导体淬火分析的新模型

最近，全球范围内已经提出了几种基于高温超导（HTS）材料的融合应用新导体设计。它们中的大多数都基于双绞带式电缆（TSTC）的思想：将一堆HTS胶带绞合，焊接并嵌入铜管中，这就是我们在这里所称的“绞线”。然后，将几股绞合在中心芯上以制成HTS电缆。最终将电缆插入不锈钢护套中，该护套为超临界氦冷却剂通过股间间隙的强制流动提供了机械支撑和限制。TSTC中积累的热梯度使得为低温超导磁体开发的一维热工液压模型不适合研究快速瞬变（例如淬火传播）。这里介绍了一个新模型，
