1.3 GHz超导射频（SRF）技术是我国ILC和未来XFEL、ERL工程的关键技术之一。为了开发1.3 GHz SRF技术，IHEP已经开始了一项建立SRF加速单元的计划。该单元包含一个9单元1.3 GHz超导腔，一个短的低温振荡器，一个高功率输入耦合器，一个调谐器，一个低电平RF系统等。该计划还包括SRF实验室升级，这将允许该单元在IHEP建造和测试。该装置将用于1.3 GHz SRF系统集成研究、高功率水平测试和未来可能的波束测试。在本文中，我们报告了最近的R&D的状态，这一计划。我院研制的第一个大晶粒低损耗9室超导高频腔在首次垂直测试中达到20 MV/m。原型调谐器和LLRF系统进行了测试。第一个1.3GHz高功率输入耦合器的制作已经完成，低温振荡器正在制作中。几个关键的SRF设施（CBP，BCP，HPR，光学检测相机，预调机等）9单元腔体加工成功调试并投入运行。
1.3 GHz superconducting radio-frequency (SRF) technology is one of the key technologies for the ILC and future XFEL and ERL projects in China. With the aim to develop 1.3 GHz SRF technology, IHEP has started a program to build an SRF Accelerating Unit. This unit contains a 9-cell 1.3 GHz superconducting cavity, a short cryomodule, a high power input coupler, a tuner, a low level RF system etc. This program also includes the SRF laboratory upgrade, which will permit the unit to be built and tested at IHEP. The unit will be used for the 1.3 GHz SRF system integration study, high power horizontal test and possible beam test in the future. In this paper, we report the recent R&D status of this program. The first large grain low-loss shape 9-cell superconducting RF cavity made by IHEP reached 20 MV/m in the first vertical test. The prototype tuner and LLRF system were tested. The first 1.3 GHz high power input coupler fabrication was finished and the cryomodule is under fabrication. Several key SRF facilities (CBP, BCP, HPR, optical inspection camera, pretuning machine etc.) for 9cell cavity processing were successfully commissioned and in operation.
