A Strong-Strong Simulation on the Beam-Beam Effect in a Linac/Ring B Factory
Since the inherently low emittance required by the linac/ring B Factory implies high disruption for the linac bunch, previous investigations of the beam-beam tune shift limit may not apply. A strong-strong simulation scheme was developed based on a macroparticle model to simulate beam-beam interaction in this situation self-consistently. Included in the ring dynamics are linear betatron oscillations and synchrotron motion, as well as transverse and longitudinal damping and quantum excitation. As a benchmarking test, the coherent quadrupole effect in a ring/ring collider was observed by the simulation. The code was then used to study the stability of the storage ring bunch in alinac/ring collider, and yielded strong synchro-betatron coupling due to the deep envelope modulation of the linac bunch. It was, however, observed that when intial conditions for the linac beam were properly chosen to match the focusing provided by the ring beam at IP, the beam-beam tune shift limit of the ri
