| 英文摘要 | For performing mini-beta scheme in the Beijing Electron-Positron Collider (BEPC), high RF voltage is supplied for shortening the bunch length, but results in the luminosity decrease. This is the special phenomenon of beam-beam on BEPC, which limits the performance of mini-beta scheme. The work is aiming to explain the special phenomenon and overcome it. The conclusion of theoretic analysis, simulation and machine study is that, for BEPC, the bunch length influences the beam-beam interaction mainly through the "hour-glass" effect and a veraging over the betatron phase during the collision, and these two contrary effects make the luminosity to be maximum only when sigma, /beta (gamma) (the ratio of bunch length and beta function of gamma -direction) is near the optimal value, and so the luminosity decrease due to high RF voltage can be avoided. |
