28 GHz Nb3Sn ECR离子源磁体的模具设计、线圈制造和原型线圈性能验证

在世界范围内，已经开发了几种超导电子回旋共振（ECR）离子源，并使用铌钛磁体作为重离子加速器。为了探索利用高场Nb$_{3}$Sn来突破ECR磁体中Nb- ti的场极限，必须采用最先进的Nb$_{3}$Sn线圈制造技术和工具设计来解决Nb$_{3}$Sn导体的挑战性特性。在此之前，我们报道了用Nb$_{3}$Sn六极线圈构建28 GHz超导ECR离子源的总体磁体设计、导体选择和导体特性。本文介绍了Nb$_{3}$Sn六极线圈原型的制备进展。特别地，我们介绍了工具的设计，Nb$_{3}$Sn六极线圈的制造，以及用于性能验证的镜像磁铁。
