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 are under test. The first 1.3 GHz high power input coupler fabrication was finished and the cryomodule is under fabrication. Several key SRF facilities (CBP, CP, HPR, optical inspection camera, pretuning machine etc) for 9-cell cavity surface treatment and pre-tuning were successfully commissioned and in operation.
