摘　　要：系统介绍 HTS实验磁体的液氮、液氦实验和固氮浸渍实验 ,获得 78.6～ 4 .2 K不同温度下磁体的伏～安特性曲线和 Ic～ T曲线 ,在很宽的范围内研究了 HTS实验磁体性能。A HTS magnet with a central field of 2.9T at 20K wound with Bi2223/Ag tapes were studied experimentally in this paper. The experiments with the HTS magnet dipped in liquid nitrogen, in liquid helium and impregnated with solid nitrogen were carried out. The performances of the HTS magnet were studied in a wide range of temperatures with the V-I curves at different temperature from 4.2K to 78.6K and that of the critical currents of the magnet verses the operating temperatures.
