| Abstract: | It is one of the most classical experiments that measuring critical characteristics of high-temperature superconductor.This paper proposes a method that can improve the traditional test system for measuring critical characteristics of high-temperature superconductor by using the GM refrigerator and by combining the virtual instrument software LabVIEW with the data acquisition board.This test system can measure critical currents of high-temperature superconductor at different temperature,and can also measure quench propagation property.This experiment is beneficial to students to know more about superconductor characteristics and to develop precise science style. |
