The physical design and research work of China Electron Positron Collider (CEPC) is an unprecedented challenge in the field of international accelerator collider. In the simulation research, many physical phenomena must be considered, including large Piwinski angle, crab waist colliding, strong nonlinear effect, energy sawtooth, beam-beam, etc. To address this challenge, a software project APES is proposed in 2021. And this project received support from the IHEP innovative fund in 2022. The progress and future plans of APES project will be introduced in the poster.

  The Beijing Electron Positron Collider II will upgrade to extend the beam energy and the luminosity by increasing the beam current and slightly compressing the beam size, where the beam energy will be extended from 2.3 GeV to 2.8 GeV and the peak luminosity will be up to 1.1×1033\rm{cm}-2\rm{s}-1 at the optimizing beam energy of 2.35 GeV. The BEPCII upgrade is expected to result in challenging levels of beam related background in the interaction region. An precise simulating and mitigating beam background is necessary to protect the BESIII detector and increase the beam current and peak luminosity. The beam related background at BEPCII is mainly from the Touschek effect and the beam gas effect, this paper presents the recent progress of the beam background simulation and experiment.
