The local thermal disturbance will produce a joule heat. When the joule heat is larger than the minimum quench energy (MQE), it will lead to the phenomenon of a quench. The same problem exists in stacked superconducting tapes. In this article, the defects in REBCO tapes were created using the bending method. The voltage and temperature traces were measured during the quench process. The quench characteristics of the MQE and normal zone propagation velocity (NZPV) of the stacked REBCO tapes were investigated of different stacked REBCO tapes in the following configurations: two defects-free tapes; one defect-free tape and one tape with a defect; and both tapes with defects. The MQE of the stacked tapes with the defect is smaller than that of the tapes without defects, while the NZPV of the stacked tapes with the defect is larger than that of the tapes without defects.

缺陷对堆叠 REBCO 胶带的淬火性能的影响

局部热扰动会产生焦耳热。当焦耳热大于最小淬火能（MQE）时，会导致淬火现象。同样的问题存在于堆叠的超导带中。在本文中，REBCO 胶带中的缺陷是使用弯曲方法产生的。在淬火过程中测量电压和温度轨迹。研究了以下配置的不同堆叠 REBCO 带的 MQE 和法向区域传播速度 (NZPV) 的 MQE 淬火特性： 两种无缺陷带；一张无缺陷胶带和一张有缺陷胶带；和两个磁带有缺陷。有缺陷的堆叠胶带的 MQE 小于无缺陷胶带的 MQE，
