本文综述了高能物理超导探测器磁体的关键技术进展,指出铝稳定导体工艺与经验面临流失风险,并强调需通过全球合作恢复能力以支撑ILC、FCC和CLIC等未来项目。

摘要:

世界各地已经研制出多种用于粒子物理的超导探测器螺线管磁体。几乎所有粒子物理实验中的探测器磁体,其关键技术都是铝稳定超导导体。随着导体的进步,线圈制造技术也取得了进展,例如内线圈绕制技术、间接冷却、透明真空容器、使用纯铝带的失超保护方案等。基于多年来建立的技术,日本和欧洲正在为未来的大型项目,即ILC、FCC和CLIC,开展探测器螺线管设计研究。良好的力学性能与保持高RRR相结合是铝稳定导体发展的关键点。目前探测器螺线管发展面临的担忧是关键技术和经验正在逐渐流失,因为在LHC的CMS和ATLAS-CS成功之后,尚未再制造过采用铝稳定导体的大型探测器磁体。需要采取互补性努力,以恢复同等水平的专业能力,扩大研究工作,发展这些技术并将其应用于未来的探测器磁体项目。尤其是铝稳定超导体生产的工业技术需要进一步努力。与相关研究所和工业界的全球合作对于重新实现并验证所需性能至关重要。一些采用传统铜稳定Nb-Ti导体绕制的中型实验探测器螺线管需要精确控制磁场分布。目前在磁场设计技术方面正在开展高精度仿真、线圈制造技术以及磁场分布控制方法的研发工作。

英文摘要:

Various superconducting detector solenoids for particle physics have been developed in the world. The key technology is the aluminum-stabilized superconducting conductor for almost all the detector magnets in particle physics experiments. With the progress of the conductor, the coil fabrication technology has progressed as well, such as the inner coil winding technique, indirect cooling, transparent vacuum vessel, quench protection scheme using pure aluminum strips and so on. The detector solenoids design study is in progress for future big projects in Japan and Europe, that is, ILC, FCC and CLIC, based on the technologies established over many years. The combination of good mechanical properties and keeping a high RRR is a key point for the development of Al-stabilized conductor. The present concern for the detector solenoid development is to have been gradually losing the key technologies and experiences, because large-scale detector magnets with Al-stabilized conductor has not been fabricated after the success of CMS and ATLAS-CS in LHC. Complementary efforts are needed to resume an equivalent level of expertise, to extend the effort on research and to develop these technologies and apply them to future detector magnet projects. Especially, further effort is necessary for the industrial technology of Al-stabilized superconductor production. The worldwide collaboration with relevant institutes and industries will be critically important to re-realize and validate the required performances. Some detector solenoids for mid-scale experiment wound with conventional copper-stabilized Nb-Ti conductor require precise control of magnetic field distribution. The development efforts are on-going in terms of the magnetic field design technology with high precision simulation, coil fabrication technology and control method of magnetic field distribution.
