为了拓展固体复合型超导体低温稳定性的基础研究，挖掘其潜力，提出了利用高温超导带束作为低温超导电缆稳定剂的混合型超导体。由于HTS的有效电阻率明显低于等截面积的纯金属，因此一束HTS带材可以作为一种很好的稳定剂来获得高电流密度。通过对LHD螺旋线圈用铝稳定超导体的改性，进行了小样实验，考察了其低温稳定性。
Hybrid-type superconductors are proposed by utilizing a bundle of high-temperature superconducting (HTS) tapes as a stabilizer of low-temperature superconducting (LTS) cables in order to extend the basic research on the cryogenic stability of solid composite-type superconductors and to explore its potential. Since the effective resistivity of HTS is significantly lower than that of pure metals of equivalent cross-sectional area, a bundle of HTS tapes may work as a good stabilizer to achieve high current density. Short sample experiments have been carried out by modifying the aluminum-stabilized superconductor used for the LHD helical coils and the cryogenic stability was examined.
