摘要

The High Energy Photon Source (HEPS) is the first fourth-generation synchrotron radiation light source project in Asia, 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. In this review paper, the design as well as the commissioning progress of the HEPS accelerator and beamlines are reported, where the challenges faced and corresponding measures during the design and commissioning are introduced.
