Реферат: The part of the ongoing study of the future circular collider (FCC) [1] is an electron positron machine with center of mass energy from 90 to 350 GeV. Crab waist collision scheme [2, 3] and small (1 mm) vertical beta function at the interaction point (IP) provide superior luminosity. At the top energy, radiation in the field of the opposite bunch (beamstrahlung) [3–5] limits the beam lifetime and therefore achievable luminosity. Beamstrahlung influence depends on momentum acceptance of the lattice, and acceptance of 2% provides acceptable lifetime. The small value of vertical beta function enhances effects of nonlinear chromaticity. The present work describes principles used in design and optimization of FCC-ee momentum acceptance optimization.
