Abstract

In order to assemble a magnet using second generation (2G) high temperature superconducting (HTS) tapes, one usually stacks the pancakes using the joint method. When joining the tape, it is important to keep the initial characteristics of the original tape. When two tapes are joined, appropriate pressure should be applied to each tape. The reason is that insufficient or excessive forces on the joined surface affect the inherent characteristics of each tape, such as the critical current and the n-value. The generated heat flux on the joined tapes is related to the quench occurrence when the magnet is affected by unexpected disturbance. In this study, the effect of the external disturbance on the joined tapes was examined. The experiments were carried out with a single tape and two kinds of joined tapes. The joints were exposed to various pressures. The stability and recovery characteristics of the experimental samples were analyzed and compared with each other.
