Description
The High Energy Photon Source (HEPS) is the first fourth-generation synchrotron radiation light source project in China, with an electron energy of 6 GeV, a circumference of 1360 m and a natural emittance of a few tens of picometers. As a green-field light source, the HEPS construction started in 2019 and is scheduled to be completed in 2025. Now civil construction, component fabrication and tunnel installation have been complected, and multipole milestones have been achieved in commissioning of the accelerator and beamlines. The HEPS pass the performance acceptance review in October 2025. We will report the construction process, the commissioning progress of the HEPS and the experience of pilot user operation, where the challenges faced and corresponding measures during the commissioning are introduced.
