A beam optics scheme has been designed [ 1 ] for the Future Circular Collider- e + e − (FCC-ee). The main characteristics of the design are: beam energy 45 to 175 GeV, 100 km circumference with two interaction points (IPs) per ring, horizontal crossing angle of 30 mrad at the IP and the crab-waist scheme [ 2 ] with local chromaticity correction.

A design of beam optics will be presented for the FCC-ee double-ring collider. The main characteristics are 45 to 175 GeV beam energy, 100 km circumference with two IPs/ring, 30 mrad crossing angle at the IP, crab-waist scheme with local chromaticity correction system, and "tapering" of the magnets along with the local beam energy.

Several Topics on Beam Dynamics in FCC-ee
/ Oide, Katsunobu (KEK, Tsukuba) ; Aumon, Sandra (CERN) ; Charles, Tessa (CERN) ; El Khechen, Dima (CERN) ; Shatilov, Dmitry (Novosibirsk, IYF) ; Tydecks, Tobias (CERN)
The FCC-ee is a double-ring $e^+e^-$ collider to be installed
in a common tunnel of∼ 100km circumference, as a po-
tential first step before the FCC-hh hadron collider. Several
studies on the beam dynamics at FCC-ee: low emittance
tuning, dynamic aperture, beam blowup with/without beam
beam, are introduced in the paper..

Local chromatic correction scheme and crab-waist collisions for an ultra-low beta* at the LHC
/ Abelleira, Jose Luis (Ecole Polytechnique, Lausanne ; CERN) ; Russenschuck, Stephan (CERN) ; Tomas, Rogelio (CERN) ; Zimmermann, Frank (CERN) ; Ohmi, Kazuhito (KEK, Tsukuba) ; Milardi, Catia (Frascati) ; Zobov, Mikhail (Frascati) ; Shatilov, Dmitry (Novosibirsk, IYF)
We discuss potential merits and the parameter range of interest for a possible crab-waist collision scheme at the LHC, and report preliminary optics studies of a local chromatic correction scheme with flat beams (β*x ≫ β*y ), which could boost the LHC luminosity by about an order of magnitude and would also allow for crab-waist collisions..

Beam Dynamics Challenges for FCC-ee
/ Zimmermann, Frank (CERN) ; Benedikt, Michael (CERN) ; Oide, Katsunobu (KEK, Tsukuba) ; Bogomyagkov, Anton (Novosibirsk, IYF) ; Levichev, Evgeny (Novosibirsk, IYF) ; Migliorati, Mauro (INFN, Rome ; Roma U.) ; Wienands, Uli (CERN)
The goals of FCC-ee include reaching luminosities of up to a few 1036 cm-2s-1 per interaction point at the Z pole or some 1034 cm-2s-1 at the ZH production peak, and pushing the beam energy up to ≥175 GeV, in a ring of 100 km circumference, with a total synchrotron-radiation power not exceeding 100 MW. A parameter baseline as well as high-luminosity crab-waist options were described in [1] and [2], respectively. [...]

We discuss potential merits and the parameter range of interest for a possible crab-waist collision scheme at the LHC, and report preliminary optics studies of a local chromatic correction scheme with flat beams (beta_x*>>beta_y*), which could boost the LHC luminosity by about an order of magnitude and would also allow for crab-waist collisions..

Progress in the Design of Beam Optics for FCC-ee Collider Ring*
/ Oide, Katsunobu (KEK, Tsukuba) ; Benedikt, Michael (CERN) ; Blondel, Alain (Geneva U.) ; Bogomyagkov, Anton (Novosibirsk, IYF) ; Boscolo, Manuela (Frascati) ; Burkhardt, Helmut (CERN) ; Holzer, Bernhard (CERN) ; Koratzinos, Michael (Geneva U.) ; Levichev, Evgeny (Novosibirsk, IYF) ; Milanese, Attilio (CERN) et al.
The beam optics for the FCC-ee collider has been updated: (a) the layout is adjusted to a new footprint of FCC-hh, (b) the design around the interaction point is refined considering a number of machine-detecor interface issues, (c) the arc lattice is refined taking realistic magnet designs into account, (d) the β^{*} and betatron tunes are re-optimized according to recent results of the beam-beam simulations, and more. These changes make the collider design more realistic without performance degradation..
