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

Abstract

For practical application, stability investigation of high temperature superconductor (HTS) is of great importance. An insert set-up has been developed at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). Measurements are performed as a function of transport current and magnetic field for several operating temperatures between 30 and 50 K. This work focuses on the design of insert set-up and the estimation of normal zone propagation velocity (Vnzp) and minimum quench energy (MQE). The experimentally obtained temperature dependence of Vnzp is compared with a simplified adiabatic model.
