Recent progresses in the second generation REBaCuO (RE123) coated conductor (CC) have paved a way for the development of superconducting solenoids capable of generating fields well above 23.5 T, i.e. the lim it of NbTi-N bSn-based magnets. However, the RE123 magnet still poses several fundamental and engineering challenges. In this work we review the state-of- the-art of conductor and magnet technologies. The goal is to illustrate a close synergetic relationship between evolution of high-field magnets and advancement in superconductor technology. The paper is organized in three parts: (1) the basics of RE123 CC fabrication technique, including latest developments to improve conductor performance and production throughput; (2) critical issues and innovative design concepts for the RE123-based magnet; and (3) an overview of noteworthy ongoing magnet projects.
第二代稀土钡铜氧（RE123）涂层导体（CC）的最新进展为开发能够产生远高于23.5 T磁场的超导螺线管铺平了道路，23.5 T是基于铌钛 - 铌锡的磁体的极限。然而，RE123磁体仍然面临一些基本和工程挑战。在这项工作中，我们回顾了导体和磁体技术的现状。目的是说明高场磁体的发展与超导体技术进步之间的紧密协同关系。本文分为三个部分：（1）RE123 CC制造技术的基础，包括提高导体性能和生产产量的最新进展；（2）基于RE123的磁体的关键问题和创新设计概念；（3）对正在进行的值得关注的磁体项目的概述。
