| Abstract: | A 40-T hybrid magnet was under construction at High Magnetic Field Laboratory,Chinese Academy of Sciences.The superconducting outsert,which was based on cable-in-conduit conductor(CICC) technology,would be cooled with forced flow of supercritical helium at 4.5K.The friction faction in CICC was one of the most important parameters for determining the optimal inlet pressure and mass flow rate of the cooling loops.In this paper,we presented and discussed an experiment on the dummy conductor,whose goal was to d... |
