摘　　要：射频超导腔是超导电子加速器的核心部件,1.3 GHz 9cell超导腔被欧洲X射线自由电子激光、美国直线加速器相干光源二期等大科学装置采用,也是中国在建上海硬X射线自由电子激光装置、未来环形正负电子对撞机、国际直线对撞机等项目的关键设备。9cell超导腔的国产化、产业化对我国大科学装置的建设非常重要。本文在简要介绍超导腔用途及国际上椭球腔技术发展的基础上,较为详细地介绍了北京大学1.3 GHz椭球型单腔和9cell超导腔的发展及研究成果。Superconducting RF(SRF) cavity is the core element of a superconducting linear accelerator. The 1.3 GHz 9-cell cavity is adopted by European X-ray Free Electron Laser and Linac Coherent Light Source Ⅱ, and it is also the key equipment for Shanghai Hard X-ray Free Electron Laser Facility, the future Circular Electron-Positron Collider and International Linear Collider, etc. The domestication and industrialization of the 9-cell SRF cavity is very important for our country’s large scale scientific facilities based on superconducting accelerator. Based on the brief introduction of the application of superconducting cavityand the development of ellipsoidal cavity technologies in the world, the development and recent results of the 1.3 GHz ellipsoidalsingle cavity and 9-cell superconductingcavity at Peking University are reported in detail.
