Abstract:

Please note that the we kindly ask you when connecting to this seminar to mute your microphones and cameras in order to have a good connection.

Inhomogeneous temperature elevations, also called hot spots, occurring in second generation high-temperature superconductor (2G HTS) tapes may lead to their destruction. A better understanding of inhomogeneous quenches would contribute to develop strategies to better protect superconducting devices based on 2G HTS tapes against hot spots.

The aim of this seminar is to present investigations about the current redistribution around a dissipative zone in a 2G HTS tape with a combination of experiments consisting of the visualization of bubble generation on the surface of a HTS tape and 3D electro-thermal numerical simulations based on the finite element method (FEM).
