摘要

布鲁克海文国家实验室(BNL)拥有独特的直接风(DW)线圈缠绕技术,用于制造复杂的多功能超导磁体。其中一些磁体已经集成在目前运行的加速器综合体中,如HERA, BEPC, JPARC和RHIC。这些多层磁铁不需要电缆磁铁所需的定制生产工具。电子离子对撞机(EIC)项目计划在IP6相互作用点的大多数磁体上使用DW技术。为了研究高磁场(和高洛伦兹力)下直风磁体的性能,研制了高场直风磁体。它由三层双层线圈组成,在半径为38毫米的芯轴上缠绕着直径为6 - 1 1.575毫米的导体。对该磁体在约4 t的导体上进行了峰值磁场测试,讨论了磁体在反复自淬条件下的训练行为,以及在点加热器诱导淬火条件下的淬火行为。

Test Results for the High Field Direct Wind Magnet
Brookhaven National Laboratory (BNL) has a unique Direct Wind (DW) coil winding technology which is used to fabricate complex multi-functional superconducting magnets. Some of these magnets have been integrated in currently operational accelerator complexes, such as, HERA, BEPC, JPARC, and RHIC. These multi-layer magnets do not require custom production tooling necessary for cabled magnets. The Electron Ion Collider (EIC) project is planning to use DW technology for most of the magnets at the Interaction Point IP6. To study the performance of a direct wind magnet at high magnetic field (and high Lorentz force), a High Field Direct Wind (HFDW) magnet was manufactured. It consists of three double layer coil-sets wound with a six-around-one 1.575 mm diameter conductor on a 38 mm radius mandrel. This magnet was tested up to peak magnetic field on the conductor of approximately 4 T. This paper discusses 1) the magnet training behavior under repeated spontaneous quenches, and 2) quench behavior with spot heater induced quenches.

期刊介绍: IEEE Transactions on Applied Superconductivity (TAS) contains articles on the applications of superconductivity and other relevant technology. Electronic applications include analog and digital circuits employing thin films and active devices such as Josephson junctions. Large scale applications include magnets for power applications such as motors and generators, for magnetic resonance, for accelerators, and cable applications such as power transmission.
