Quench dynamics study in 2nd generation HTS tapes

The faster quench detection is required for high temperature superconductor (HTS) to avoid the local damage of conductor due to overheating. This problem is particularly challenging for high temperature superconducting magnets due to the slower normal zone propagation velocity (NZPV) in comparison to low temperature superconductor (LTS). As a result, quench detection and protection for HTS coils is matter of concerned for fusion community working for the 2nd generation high field tokomak. The Di-BSCCO HTS tape samples of critical current around 160 A are selected to study the quench dynamic experiment. The Normal zone voltage rise and the temperature evolution after thermal quench were experimentally measured in Di-BSCCO tapes. The measured voltage and temperature signals have been analysed and elaborated in this paper.
