Measurement system of test facility for the superconducting short-sample wire

A self-developed real-time measurement system of test facility for the superconducting shortsample wire is presented. It includes the measurement and data acquisition of such five different parameters as temperature, pressure, liquid level, electric current and electric voltage. Based on the computer operating system and MCGS configuration software, the real-time display and record of these data are realized by use of A/D data acquisition card and by selection of the sensors and measurement method. The advantages of the measurement system are simple, convenient and reliable. With the completion of the superconducting short-sample wire test and the superconducting magnet quench experiment, some results also are given. These results indicate that the system can meet the measurement requirements of all parameters. The measurement system can integrate the cryogenic data measument with the electric measurement and gives a helpful reference for the data measure of the cryogenic system applied in the field of the superconduction.
