Abstract

In this work we address the shift from Low Temperature Superconductor (LTS) to High Temperature Superconductor (HTS) magnets presently occurring in the development of machines for controlled thermonuclear fusion with magnetic confinement. This shift implies several new challenges, which cannot be ignored in the design and modelling of the future HTS magnets. In this work, we identify the modelling needs driven by the adoption of HTS cables and coils technology for fusion machines. In particular, the characteristic times characterizing the development of the main physical phenomena occurring in HTS tapes, stacks and conductors are derived. These characteristics times in turn have a significant impact on the requirements of strong or weak coupling between different physics in the modelling of HTS magnets.

紧凑型聚变反应堆中高温超导CICCs运行的特征时间尺度

在这项工作中，我们解决了从低温超导体（LTS）到高温超导体（HTS）磁体的转变，目前发生在磁约束控制热核聚变机器的发展中。这种转变意味着在未来高温超导磁体的设计和建模中不可忽视的几个新挑战。在这项工作中，我们确定了由采用高温超导电缆和线圈技术驱动的建模需求。特别地，导出了表征高温超导带、堆和导体中发生的主要物理现象发展的特征时间。这些特性时间反过来对高温超导磁体建模中不同物理之间强耦合或弱耦合的要求产生重大影响。
