| The High Energy Photon Source (HEPS) is a 6 GeV, 1.3 km storage ring light source being built in Beijing, China. To get an ultralow emittance, high-gradient quadrupoles, combined-function magnets and longitudinal gradient dipoles are adopted in the design of the storage ring and the lattice is compact. The fringe field effects and cross talk between magnets may result in performance distortion of the machine, the impacts of these effects are worth studying. To this end, several methods based on one-dimensional and three-dimensional magnetic fields are used to model different kinds of magnets of the HEPS storage ring and the cross talk between magnets are simulated and evaluated. In this paper, we will introduce detailed modeling methods and the impact of fringe field effects and cross talk on the linear optics of the HEPS storage ring. | ||
