Abstract：
A beam photoelectron instability may arise in high energy storage rings when the multibunch positron beam interacts with the photoelectrons which are produced in the beam tube by synchrotron radiation. This instability gives rise to a big interest for the accelerator physicists in recent years as a new mechanism has been involved in this phenomenon study. It is very important for the particle factories as there are strong multi-bunch positron beams to be operated. The experimental observations are carried out in the Beijing Electron Positron Collider (BEPC) under the cooperation between IHEP, China and KEK, Japan, and the simulation studies are presented in this paper.
