Modeling thermal destruction of superconducting state in non-homogeneous HTS bridge

Abstract

Thermal destruction of the superconducting state has been investigated in the HTS bridge with given discontinuity. Temperature distribution and current amplitude distribution have been modeled along the bridge. Modeling has been done taking into account the dependence of the critical current density on temperature. The temperature distribution and the current amplitude distribution in case of the thermal destruction have been obtained at different input power levels. Analysis of the results has shown the influence of the thermal destruction on the current distribution in the bridge and the transmission coefficient 21 .
