Description
Summary:Superconductive switches with a high-critical-current (100–200 A) capability have been shown to be practical. Materials thought most likely to be effective as high-critical-current pressure contacts were tested. The effects of oxidation, preloading at room temperature, and transverse magnetic fields on the critical-current capacity of contacts were studied. The relationship of the critical current of the junction to its normal-state resistance is investigated for Pb contacts.
