Special Beam Physics Seminar
We discuss the impact of the beam-beam interactions on RUN IIa operation at present parameters.
In RUN IIa the Tevatron is operating with 36 proton and 36 anti-proton bunches. Each anti-proton
bunch experiences 72 long range beam-beam interactions at injection, two head-on and 70 long-rang
beam-beam interactions at collision. At injection, we look at the liner and non-linear contribution
of beam-beam effects under present machine conditions. At collision, we look at the beam-beam
effects under design machine conditions, since anti-proton and proton lifetimes are not much
affected by beam-beam at present intensities. Comparisons of calculations with observations
and experiments are also presented in this report.
