Abstract
A persistent current switch (PCS) is used for superconducting applications, such as superconducting magnetic energy storage (SMES) system. The authors have proposed a mechanical switch of YBCO bulk as a mechanical PCS. From the previous research, it turned out that there were improvements of reducing contact resistance and load in the YBCO switch. In this paper, the phenomenon of the YBCO-deposited metal interface was reported. The authors experimentally investigated as one side curvature silver sample (above contactor), other side YBCO sample deposited silver layers (below contactor). Additionally, the contact area of the sample was analyzed with finite element method (FEM). This analysis result may lead to the elucidation of a contact mechanism with the contact surfaces deposited metal.
