Investigation of critical current on magnetic and non-magnetic HTS tape
, 2018 Critical current is a key parameter for HTS tapes, which is able to determine the performance of superconducting devices. In this study, we chose two kinds of HTS tape, with magnetic and non-magnetic substrates, to experimentally investigate their ...

Design of Automotive HTS Magnets for High-speed Electric Maglev
机车电传动, 2019 The superconducting magnet based on the second-generation high-temperature superconducting (HTS) tape can work at 15 K to 77 K. Compared with the low-temperature superconducting (LTS) magnet working below 4.2 K (the liquid helium temperature zone), the ...

Transversal thermal conductivity of HTS tapes
Superconductivity refers to the ability of certain materials to conduct electricity without any resistance. This phenomenon is only possible below a specific critical temperature threshold, usually extremely low temperature. When designing superconducting devices, such as superconducting magnets, ensuring constant low-enough-temperature is essential to

The critical currents of a twisted single-tape were measured at 4.2 K in fields up to 17 T. It was confirmed that the critical current of a twisted-tape was similar to that of a flat tape in c-axis fields. Based on the single-tape critical-currents, a 40-

Transversal Thermal Conductivity of HTS Tapes: Analytical Method vs Measurements
Design of ReBCO HTS magnets requires reliable data about the tape and insulation thermal conductivities. Material properties represent one of the largest uncertainties when simulating the HTS magnet thermal behavior during magnet cooling, operation, and ...
