Abstract :
We consider the combined effects of the beam-beam interaction and the lattice nonlinearities for one specific design of the muon collider ring. The beam-beam interaction is represented by a thick gaussian lens, and the ring is described by a 9th-order Taylor map. At the single-particle level we compare the tune footprints and the dynamic aperture with and without the beam-beam effect. At the multiparticle level, using a “weak-strong” description of the beam-beam interaction, we compare the time evolution of the rms beam sizes with a linear lattice map and with the full nonlinear map
