Database of performance testing of the iron-based superconductor inserted coils under high magnetic field

The iron-based superconductor (IBS) is considered to have a great potential application under high magneticfield. It is one of the important steps to carry out the research on high magnetic field IBS inserted coil in order topromote the practical application of IBS. We developed a type of Ba122 single and double pancake inserted coilswith 35 mm outer diameter, and its performance has been tested at 4.2 K in the background magnetic field of 30T, in contrast, the transport critical current (Ic) of 30mm short tape form the same batch was measured at 4.2 K inthe background magnetic field of 30 T.

铁基超导体（iron-based superconductor, IBS）被认为在高磁场环境下具备极高的应用潜力。推动铁基超导体的实用化进程，开展高磁场下铁基超导体插入式线圈的相关研究是关键环节之一。本研究研制了一款外径为35毫米的Ba122型单饼及双饼插入式线圈，并在4.2K、背景磁场30T的条件下对其性能开展了测试；作为对照，同一批次的30毫米短胶带样品的传输临界电流（transport critical current, Ic）也在4.2K、背景磁场30T的环境下完成了测量。
