Long-Term Simulation of Beam-Beam Effects in the Tevatron at Collision Energy

The beam-beam effect is a significant source of non-linearities in the Tevatron. We have developed a code which allows us to estimate its contribution to the finite lifetime of the anti-proton beam, both at collision and injection energy, by tracking realistic particle distribution for a high number of terms and extrapolating from the particle loss rate. We describe the physical modeling underlying the code and give benchmarking results.
