超导体内没有电阻和焦耳耗能,因此一旦迭入电流,此电流就可以一直存在,其所产生的磁场也能在不外力做功的情况下永速保持。因此有一种电磁铁用超导体做螺线圈,这种磁铁就被成为超导磁铁。
2008年9月,对撞机正开始第一轮质子循环时,两块超导磁铁的连接处发生毁灭性的故障。
The machine had just begun circulating its first protons in September 2008 when a connection between two of its superconducting magnets failed catastrophically.
从这个月开始——并一直持续四个星期——粒子加速器都要对绕着它的超导电磁铁旋转的铅离子进行加速。
Starting this month - and continuing for four weeks - the particle accelerator will be speeding lead ions around its superconducting electromagnets.
