Simulation Study of Head-On Beam-Beam Compensation with Realistic Rhic Lattices ∗ (original) (raw)

To reduce the beam-beam resonance driving terms with half head-on beam-beam compensation in the RHIC polarized-proton operations, the betatron phase advances between the interaction point IP8 and the center of the electron lenses located around IP10 should be kπ ,w herek is an integer. Realistic beam-beam compensation lattices meeting the phase advance requirements were developed and used in the beginning of 2013 polarized proton run, although head-on beam-beam compensation was not implemented yet. In this article, with these lattices and a 6D weak-strong beam-beam simulation model, we calculate the proton dynamic apertures with and without beam-beam compensation. Preliminary results with second order chromaticity correction are also presented.
