Investigation of Electro-physical and Physical-mechanical Properties of HTS 2G Tapes

High temperature superconducting tapes of 2nd generation (HTS 2G) are being manufactured by several companies worldwide, which use different methods of fabrication of superconducting layers that affect the behaviour of HTS 2G tapes in actual practice. This paper presents the results of the study of HTS 2G tapes delamination process, the influence of alternating temperature impacts on critical current and the behaviour of current carrying capacity of HTS 2G tapes in external magnetic fields. The abovementioned problems can arise in almost any case of designing devices based on HTS 2G tapes. Furthermore, the developed measuring techniques are very important for controlling of output parameters of HTS 2G tapes that are to be manufactured in NRC “Kurchatov institute”.
