Abstract

A new low-loading HTS Superconductive-Normal (S-N) current switch using a YBCO thin film stripe is introduced in this paper. Low cost 2.45 GHz microwave signal is applied as the triggering method. Two configuration patterns, cavity layout and transmission line layout, have been tested in the experimental environment. Reliable 100 ms S-N switching is observed with transmission line layout where the loading current is set below 5% of the critical current (Ic). This work demonstrates that a high frequency RF signal is an applicable approach for S-N switch development.
