The part of the ongoing study of the future circular collider (FCC) is an electron positron machine with center of mass energy from 90 to 350 GeV. Crab waist collision scheme 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) limits the beam lifetime and therefore...

Layout and lattice of FCC-ee are being optimised for precision studies and rare decay event observations in the range of 90 to 350 GeV center of mass energy. To reach luminosities in the order of $10^{35}$ cm$^{-2}$s$^{-1}$ extremely small vertical beta functions of 1 - 2 mm are required at the two interaction points. The strong focusing by the final doublet quadrupoles drives the absolute...

In order to avoid the pretzel orbit, CEPC is proposed to use partial double ring scheme in CDR. In this paper, a general method of how to make an consistant machine parameter design of CEPC with crab waist by using analytical expression of maximum beam-beam tune shift and beamstrahlung beam lifetime started from given IP vertical beta, beam power and other technical limitations was developed....

CEPC was proposed as an electron and positron collider ring with a circumference of 50-100km to study the Higgs boson. Since the proposal was made, the lattice design for CEPC has been carried out and a preliminary conceptual design report has been written at the end of 2014. In this paper, we will describe the principles of pretzel scheme, which is one of most important issues in CEPC lattice...
