TI - Interaction region for crab waist scheme of the Future Electron-Positron Collider (CERN) J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Design study of the accelerator that would fit 80-100~km tunnel called Future Circular Colliders (FCC) includes high-luminosity e⁺e⁻ collider (FCC-ee) with center-of-mass energy from 90 to 350~GeV to study Higgs boson properties and perform precise measurements at the electroweak scale. Crab waist interaction region provides collisions with luminosity higher than 2×10³⁶~cm⁻²sec⁻¹ at beam energy of 45~GeV. The small values of the beta functions at the interaction point and distant final focus lenses are the reasons for high nonlinear chromaticity limiting energy acceptance of the whole ring. The paper describes interaction region for crab waist collision scheme in the FCC-ee, principles of tuning the chromaticity correction section in order to provide large energy acceptance.
