介绍了第二代(2G)高温超导线材和线圈技术的最新发展，强调了2G高温超导线材在与许多应用相关的苛刻操作条件下运行的能力，包括运输用直线电机。讨论了在各种线圈结构和应用中使用的挑战。结构基板、缓冲层、HTS层和稳定器的2G导线架构使2G导线能够承受高应力水平，同时提供轻便紧凑磁体所需的高电流密度。超强2G高温超导细线(0.1 mm)的高绕组电流密度已被用于多个线圈演示，其中一个产生的中心磁场超过26.8T，还将讨论该线的定制能力(稳定性、绝缘、交流损耗)以适应各种运行参数。
Recent developments in second-generation (2G) HTS wire and coil technology are presented highlighting the ability of 2G HTS wire to function under demanding operating conditions associated with many applications including linear motors for transportation. The challenges of use in various coil constructions and applications are discussed. The 2G wire architecture of a structural substrate, buffer stack, HTS layer, and stabilization enables the 2G wire to tolerate high stress levels while providing the high current density required for lightweight, compact magnets. The high winding current density that is available with SuperPower's thin (0.1 mm) 2G HTS wire has been utilized in several coil demonstrations, including one generating central fields in excess of 26.8 T. The ability of the wire to be tailored (stabilization, insulation, ac losses) to fit various operating parameters will also be discussed.
