Beam-effect simulation program SBBE for independently developing parallel positive and negative electron storage rings. Beam force is calculated by solving the Poisson’s equation in free space. Radiative damping and random effects are introduced into the single-turn transmission map. Using it for BEPC The results show that SBBE can well reproduce the phenomenon caused by beam effect in BEPC and have some predictive ability.This work is a new method to simulate the beam of BEPCⅡ Effect Simulation Study.
