Effect of the beam-beam interactions on the dynamic aperture and amplitude growth in the LHC

OSTI ID:7832
The dynamic aperture at collision energy is determined pri-marily by the nonlinear fields of the IR quadrupoles but is also influenced by the beam-beam interactions. We revisit the choice of the crossing angle that maximizes the dynamic aperture with an accurate modeling of the long-range inter-actions and use of the present values of the IR quadrupole field harmonics. A separate but related issue we address is the amplitude growth of particles in the beam halo due to the long-range interactions.
