Abstract

Purpose

The High-Energy Photon Source (HEPS) is a 6 GeV storage ring-based light source under construction in Beijing, China. Its accelerator consists of a 6 GeV storage ring, a full-energy booster, an S-band normal-conducting 500 MeV linac, and three transport lines. As the beginning of HEPS, a stable linac is quite important, which needs a qualified waveguide distribution system to transmit microwave power from klystrons to accelerating structures.

Methods

Installation and high-power conditioning of the HEPS linac were performed from February to September 2022. The assembly and conditioning of the waveguide distribution system were completed in April and July, respectively. The design of the waveguide distribution system began in 2018 and was finalized at the end of 2020 after multiple iterations.

Results

Owing to careful design, fabrication, and assembly preparation, the assembly and conditioning of the system proceeded smoothly and considerable time was saved.

Conclusion

The entire process from the design to the ultimate realization of the system is introduced in detail in this paper. Satisfactory measurement results were obtained for some waveguide components.
