本文叙述了用脉冲场对三种国产 A-15超导材料高场临界电流的测试。指出样品表面的铜层对低场测量结果有显著的影响。在一定的铜厚下对某些样品甚至可在低至6T 的脉冲磁场下获得和稳恒场一致的数据。
This paper describes the use of pulsed field test of the domestic field A-15 high-field critical current. It is pointed out that the copper layer on the sample surface has a significant effect on the low-field measurement results. At some copper thickness, some samples are even consistent with steady-state data at pulsed magnetic fields as low as 6T.
