Development of a Normal Zone Propagation Set-Up for YBCO Superconducting Tape

In order to study controlled quench behavior of high temperature superconducting (HTS) materials, an experimental set-up has been developed at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The device was designed as an insert set-up that can be inserted into a 14 T hybrid background field magnet at ASIPP. A quench can be initiated by the quench heater. The heat generated in the heater will transfer to the sample, causing a quench if the temperature gets high enough. The measured normal zone propagation velocity (NZPV) and minimal quench energy (MQE) of YBCO coated conductor tapes will be presented throughout a wide range of temperature, different transport current. The results from the experiment were compared with analytical model data. The experiment and results will be presented in this paper.
