Abstract :
The multibunch collision by means of a pretzel scheme to enhance the luminosity in BEPC has been studied. The modification of the lattice is carried out, the solenoid compensation and chromaticity correction are studied, the physical aperture is examined, the long range beam-beam interaction and coupled bunch instabilities are investigated. The results show that the pretzel scheme with six bunches per beam is feasible
