The High Energy Photon Source (HEPS),under construction since 2019,is located in the northern core area of Huairou Science City (HSC) and is one of HSC’s large scientific facilities. When it is commissioned,HEPS will not only be the first high energy light source in China but also one of the brightest fourth-generation synchrotron radiation facilities in the world.

HEPS complex buildings resemble a magnifying glass, thus aptly symbolizing the role of HEPS as a powerful tool for characterizing the microstructure of matter. As one of the key projects listed in the 13th Five-year Plan for national major scientific and technological infrastructure construction, HEPS is an important platform for original and innovative research in the fields of basic science and engineering. The HEPS project, undertaken by the Institute of High Energy Physics of the Chinese Academy of Sciences, comprises accelerators, beamlines and utility facilities. The estimated construction period is six-and-a-half years.
