Abstract

Rare-Earth Barium Copper Oxide (REBCO) coated conductors are an attractive option for application in high field accelerator magnets due to their high critical field and the convenience of fabrication without heat treatment compared to some other superconductors. A small REBCO accelerator magnet was previously fabricated and tested in liquid nitrogen, demonstrating over 90% critical current retention in the coils. This paper describes the magnet re-assembly with a different support structure and its test in liquid helium at 1.8–4.5 K. The magnet quench history along with the instrumentation data is presented and discussed.

用STAR导线重新组装和测试COMB偶极磁体

稀土钡铜氧化物（REBCO）涂层导体由于其高临界场和与其他超导体相比无需热处理制造的便利性，在高场加速器磁体中应用是一个有吸引力的选择。一个小型REBCO加速器磁体先前已在液氮中制造并测试，显示线圈中超过90%的临界电流保留。本文介绍了采用不同支撑结构的磁体重组及其在1.8 ~ 4.5 K液氦中的测试。介绍和讨论了磁体淬火历史以及仪器数据。
