  The High Energy Photon Source (HEPS) is the next ring-based light source with an emittance of tens of picometers, and a circumference of about 1.3 km to be built in China soon in a few years. After 10 years' evolution, the design for the High Energy Photon Source is recently bascially determined. We will report the lattice design and physics studies on HEPS, covering issues of storage lattice design and optimization, booster design, injection design, collective effects, error study, insertion device effects, longitudinal dynamics, etc.

  For over 6 meters long straight-section of HEPS, collinear double-cryogenic permanent magnet undulator(CPMU) is designed for high energy photon users to achieve higher brightness. Angular and spatial profiles of radiation produced by the double undulator configuration have been derived analytically. The efficiency of phase shifter on improving the brightness of double-CPMU is therefore evaluated with the beam energy spread and emittance are taken into account. Optimized beta-functions of electron beam are obtained.
