英文摘要	The High Energy Photon Source (HEPS), a 6GeV green-field diffraction-limited storage ring light source, will be built in Beijing, China. The HEPS design has been evolving for about ten years, and is now mostly finished and ready for construction. The storage ring is based on a modified hybrid seven-bend achromat (7BA) design, where bending magnets with reverse bending angles and longitudinal gradients are adopted to reach an ultralow natural emittance of 34.2pm with a circumference of 1360.4m. The central slice of the dipole in the middle of the modified hybrid 7BA, with flexible magnetic field, is used as the source of the bending-magnet beamline. Moreover, alternating high- and low-beta sections are specially designed to generate and deliver X-ray synchrotron radiation with high brightness of 5x10(22)photons s(-1) mm(-2) mrad(-2) (0.1% bandwidth)(-1). Here, the HEPS storage ring design and solutions to the challenges inherent in this ultralow-emittance design are presented.
