	The High Energy Photon Source (HEPS) is a 6-GeV, kilometer-scale, ultralow-emittance storage ring light source to be built in Beijing, China. The HEPS is now under extensive design and study. In this report we will introduce the progress of the lattice design and related physics studies on HEPS, covering issues of storage ring design, booster design, injection design, collective effects, error study, insertion device effects, longitudinal dynamics, etc.

	The High Energy Photon Source (HEPS) is a 6GeV ultra-low emittance light source proposed to be built in Beijing. It will utilise a full energy booster synchrotron operating at a frequency of 1Hz as its injector. For meeting the requirement of high charge when using swap-out mode, the booster need to have the ability of beam ac-cumulation. In this paper, a FODO lattice with 4 dispersion-free straight sections is presented.

	The off-axis injection scheme is also considered at HEPS. A large beta insertion section is need in the case, which breaks the symmetry of the machine. We introduce two designs of the injection section. There exist clear difference for the dynamic aperture between the two designs. The low-order nonlinear resonance driving terms is calculated and compared. The results show a correlation between momentum acceptance and the off-momentum driving terms. We enlarge the dynamic aperture by tuning the on-momentum and off-momentum non-linear driving terms with a multi-objective optimization code.
