	The talk will mainly introduce the progress of the SHINE project in China. It is scheduled to build SHINE project in seven years which includes a superconducting rf acceleractor based on TESLA technology. From 2018, SHINE started the prototypes R&D in China, including not only the cavities fabrication, but also the surface treatment methods to reach high Q performance. The preparition of test facility will be introduced, too. The plan and latest results will be reported in the talk.

MOP029	N-Doping Studies With Single-Cell Cavities for the SHINE Project	102

	The SHINE SRF accelerator is designed to operate in CW mode with more than six hundred superconducting cavities. In order to reduce the high cost of construction and operation of the cryogenic system, high-Q cavities with nitrogen-doping technology together with tradition-ally treated large-grain cavities have been considered as two possible options. In this paper, we present N-doping studies on single-cell cavities fabricated with fine-grain and large-grain niobium.

	Aiming to high repetition rate hard X-ray facility, con-struction of Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) project has been ap-proved. During the R & D phase, prototypes fabrication of key components of 1.3GHz superconducting rf system have been proposed, especially 1.3 GHz 9-cell niobium cavities. Here the paper will present the progress of the fabrication status and performance of the prototypes, together with the analysis of not only the quality factor and gradient of the cavities. Consideration of HOM feed-throughs and absorbers are also reported.
