内容記述 | In this paper, we investigated the electrical and thermal performance of conduction-cooled Bi2212/Ag HTS coils with 4K-GM cryocooler system. First, we measured the critical current Ic for different ambient temperatures T_0 at 4.2K-40K. Experimental results revealed that I_c increased with the decrease in T_0 and was saturated at T_0 < 10K. We carried out thermal analysis considering heat generation, conduction and transfer under conduction-cooling condition, and reproduced the electrical and thermal characteristics of the conduction-cooled HTS coil, taking account of temperature dependence of specific heat and thermal conductivity of the materials. We also measured the temperature rise of Bi2212/Ag HTS coil for different continuous current levels at T_0=4.8K. Experimental results revealed the criterion of thermal runaway, which was discussed in terms of heat genaration and propagation in the test coil. | |||||
