摘　　要：射频超导加速器采用在液氦温度下工作的超导加速腔,可运行在长宏脉冲或连续波模式,同时具有较大的束流孔径,可有效减小束腔相互作用。经过半个多世纪的发展,射频超导技术已经日趋成熟,广泛应用于各种光源,并将发挥越来越重要的作用。简要介绍射频超导基本原理、应用于光源的椭球型电子超导加速腔的研制工艺、超导加速模组构成和应用于不同类型光源的超导加速腔的主要特点。Superconducting accelerator, which uses SRF cavity working at cryogenic environment, can operate in macro-pulse or CW modes. Due to its large beam aperture, the interaction between beam and cavity can be reduced remarkably. After the development of more than a half century, SRF technology is quite advanced and has been applied in different kinds of light sources. In this paper,basic principle of SRF, fabrication of elliptical SRF cavity and structure of typical cryomodule of SRF accelerator are introduced.
