Strong-weak beam-beam simulation with a six dimension symplectic code

By using a symplectic code in the six dimensional phase space, we have tried to study beam blow-up due to the combined effect of the beam-beam force and the other non-linear forces from the lattice. Tune dependence of beam blow-up was studied. With the nominal beam-beam parameters of the KEK B factory (0.05), some beam blow-up was observed in the simulation. The simulation showed that the beam-beam interaction does not affect dynamic aperture.<
