The iron-based superconductor (IBS) is considered to have a great potential application under high magnetic field. It is one of the important steps to carry out the research on high magnetic field IBS inserted coil in order to promote the practical application of IBS. We developed a type of Ba122 single and double pancake inserted coils with 35 mm outer diameter, and its performance has been tested at 4.2 K in the background magnetic field of 30 T, in contrast, the transport critical current (I_c) of 30mm short tape form the same batch was measured at 4.2 K in the background magnetic field of 30 T. In this paper, design, manufacturing and heat treatment of this coils are introduced in brief, and performance testing of this coils, as well as the analysis of test results, are presented in detail. The results show the single and double pancake inserted coils can carry high transport current at 30 T background magnetic field.

铁基超导体（IBS）被认为在强磁场下具有巨大的潜在应用。为促进IBS的实际应用，进行强磁场IBS插入线圈的研究是重要的步骤之一。我们开发了一种外径为35 mm的Ba122单层和双层薄煎饼插入式线圈，并且在30 T的背景磁场中，在4.2 K下测试了其性能，相比之下，运输临界电流（I _c）在30 T的背景磁场中于4.2 K下测量了30mm短带的相同批次。本文简要介绍了该线圈的设计，制造和热处理，并对这些线圈的性能进行了测试，并进行了测试。详细介绍了测试结果的分析。结果表明，单层和双层薄煎饼插入线圈在30 T的背景磁场下可以承载高传输电流。
