一、 自从超导材料发展到有可能大规模应用以来,高能加速器采用超导技术即成为必然的发展方向,而脉冲超导材料是制作加速器主环超导磁体的关键性基础材料.英国卢瑟福高能实验室(RHEL)和美国费米国家加速器实验室(FNAL)相继在脉冲超导电缆与磁体等方面开展了系统的研究工作.FNAL目前已进入生产磁体阶段,并正在安装加速器的一个完整的扇区. 我们采用NbTi合金微芯直径～6μm的NbTi/Cu/CuNi三组元超导股线,研制成功了填充因子达90％,可用于质子同步加速器主环磁体的脉冲超导电缆材料.
First, since the development of superconducting materials to the possibility of large-scale application, the use of superconducting high-energy accelerator technology has become an inevitable trend, and the pulse superconducting material is the production of accelerator main ring superconducting magnet key base material. Systems research has been carried out in succession on pulsed superconducting cables and magnets by the Fuzhou High Energy Laboratory (RHEL) and the Fermi National Accelerator Laboratory (FNAL) in the United States, and FALAL has now entered the production magnet stage and is in the process of installing a complete Of the sector.We used NbTi alloy micro-core diameter of ~ 6μm NbTi / Cu / CuNi three component superconducting strands, developed a successful fill factor of 90%, can be used for proton synchrotron main ring magnet pulse superconducting cable material .
