Summary

THE APPLICATION OF JOINTS WHICH CAN BE DISASSEMBLED IS STUDIED WITHIN THE FRAMEWORK OF THE DEVELOPMENT OF HIGH CURRENT (25 KILOAMPERE), HIGH POWER (0. 5 KILOW) CRYOGENIC CURRENT SUPPLIES (FLUX PUMPS). THE BEHAVIOUR OF A SCALE MODEL WITH CURRENTS UP TO 5 KILOAMPERE IS PRESENTED HERE. SEVERAL MEANS OF DIMINISHING THE JOINT RESISTANCE HAVE BEEN RESEARCHED. THE ROLE OF THE SOLDER HAS BEEN INVESTIGATED. A SIMPLE MODEL GIVES GOOD QUALITATIVE UNDERSTANDING OF THE MATTER. THE PRESENCE OF AC CURRENTS IN A CRYOGENIC CURRENT SUPPLY CAUSES CONSIDERABLY HIGHER LOSSES IN THE JOINT. A GOOD IMPRESSION OF THIS DISTRIBUTION CAN BE OBTAINED BY MEASURING THE FIELD ALONG THE JOINT.
