Marco Bonura, Carmine Senatore

摘要:

在热物理性质研究的基础上,导出了适用于$_2$ $_3$ O $_{7-x}$涂层导体在强磁场中正常区传播速度的实用公式。还提出了一个解析表达式来评估作为操作条件的函数的电流共享温度。本研究使我们能够解释在文献中广泛使用的模型框架中未完全理解的实验结果。特别是,我们提供了一个基本的理解,在REBa $_2$ Cu $_3$ O $_{7-x}$涂层导体的正常区传播速度的实验证据,可以主要由工作电流,无论施加的字段和温度。

英文摘要:

Based on a study of the thermophysical properties, we derived a practical formula for the normal zone propagation velocity appropriate for REBa$_2$Cu$_3$O$_{7-x}$ coated conductors in high magnetic fields. An analytical expression to evaluate the current sharing temperature as a function of the operating conditions is also proposed. The presented study has allowed us to account for experimental results not fully understood in the framework of the models widely used in the literature. In particular, we provided a fundamental understanding of the experimental evidence that the normal zone propagation velocity in REBa$_2$Cu$_3$O$_{7-x}$ coated conductors can be mainly determined by the operating current, regardless of the applied field and temperature.
