  The High Energy Photon Source (HEPS) is a 6-GeV, kilometer-scale, quasi-diffraction limited storage ring light source to be built in China[1]. Getting the first turn and approaching the closed orbit is very important in accelerator commissioning. In order to make first turn beam commissioning efficiently, we develop a MATLAB tool based on AT for automatic beam correction and closed orbit searching. The algorithm and simulation results are presented in this paper.

  The High Energy Photon Source (HEPS) is a new designed photon source at beam energy of 6 GeV. Due to the small beam size and increased coupling impedance with the restricted beam pipe aperture, the collective effects may bring new challenges to the physical design of the machine. The collective instabilities are estimated for different operation mode. The critical instability issues are also identified for each mode.
