【Abstract】 The solid nitrogen cooling method for HTS magnet is introduced in the paper. A HTS experimental magnet with a central magnetic field of 2.90T at 20k wound with Bi2223/Ag tapes was tested in thermal communication with a mass of solid nitrogen, the cooling and warming process curves and the I-c-T characteristics of the magnet were obtained. It shows that the solid nitrogen cooling is successful for Bi2223/Ag HTS magnet operation.更多还原
