Abstract

High-temperature superconductors (HTS) are promising for fusion applications due to their thermal stability and high current density. We introduce stacks-in-conduit conductors (SICC) as a non-twisted alternative to traditional cable-in-conduit conductors (CICC), offering simpler fabrication while maintaining performance. Two layer-wound D-shaped coils were fabricated using stacked REBCO tapes for a miniature Toroidal Field (TF) magnet. Preliminary tests demonstrated successful current transport beyond 1100 A with typical superconducting characteristics. Two variants of the D-shaped coil were tested: one wound with substandard REBCO tapes and another with manufacturer-certified REBCO tapes. Additionally, experimental results indicate that layer-winding is an effective method for constructing HTS coils without internal joints. In the planned full operation, the D-shaped toroidal coil will be tested at 20 K and an operating current of 8 kA, with the maximum magnetic field anticipated to reach around 4.5 T.

叠置高温超导导体层绕d形线圈用于小型环形磁场磁体的初步试验

高温超导体（HTS）由于其热稳定性和高电流密度而在核聚变应用中具有广阔的前景。我们介绍了导管内堆导体（SICC）作为传统导管内电缆导体（CICC）的非扭曲替代品，在保持性能的同时提供更简单的制造。采用叠层式REBCO带制备了两层缠绕的d形线圈，用于微型环形磁场（TF）磁体。初步试验表明，成功的电流输运超过1100 A，具有典型的超导特性。测试了两种不同的d形线圈：一种用不合格的REBCO胶带缠绕，另一种用制造商认证的REBCO胶带缠绕。此外，实验结果表明，分层绕组是构建无内接头高温超导线圈的有效方法。在计划的全面运行中，d形环形线圈将在20 K和8 kA的工作电流下进行测试，最大磁场预计将达到4.5 T左右。
