Future Circular Collider Feasibility Study Report Volume 2 : Accelerators, technical infrastructure and safety

In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. The FCC ‘integrated programme’, described in this report, in a first stage consists of a highest-luminosity electron-positron collider, FCC-ee, serving as Higgs, top and electroweak factory, with a subsequent energy-frontier proton-proton collider, FCC-hh, as the second stage. The FCC-ee is designed to operate at four baseline centre-of-mass energies, corresponding to the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold, always delivering the highest possible luminosities to four experiments.

Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how the FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model.

Alignment & stability challenges for FCC-ee
/ Charles, Tessa K (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech. ; Manchester U.) ; Holzer, Bernhard (CERN) ; Tomas, Rogelio (CERN) ; Oide, Katsunobu (CERN ; KEK, Tsukuba) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; Zimmermann, Frank (CERN)
In order to achieve its ultra-low vertical emittance (1 pm) and high luminosity (of up to 230 \times 10^{34}\text{ cm}^{-2}\text{ s}^{-1} per collision point), the e$^{+}$e$^{−}$ Future Circular Collider (FCC-ee) requires a well-informed alignment strategy, powerful correction methods, and good understanding of the impact of vibrations. The large ring size, high natural chromaticity, small \beta ^{*}, and the low coupling ratio make the FCC-ee design susceptible to misalignment and field errors, which if not properly addressed, threaten to increase the horizontal and vertical emittances and adversely affect the luminosity.

Third-order double-achromat bunch compressors for broadband beams
/ Björklund Svensson, Jonas (Lund U.) ; Charles, Tessa K (CERN ; Melbourne U.) ; Lundh, Olle (Lund U.) ; Thorin, Sara (Lund U., MAX-lab)
Many state-of-the-art applications for linear accelerators, such as free-electron lasers (FELs) and plasma-wakefield accelerators (PWFAs), require small normalized emittances, and PWFAs in particular are very sensitive to transverse slice offsets along the beam. Dispersive systems, such as bunch compressors, can cause different chromatic aberrations, one of which yields transverse slice offsets. [...]

Singularities of particle trajectory caustics and beam shaping in bunch compressors
/ Charles, T K (CERN ; Melbourne U.) ; Paganin, D M (Monash U.) ; Boland, M J (Saskatchewan U.) ; Dowd, R T (Australia, CSIRO, Clayton)
Caustics are a common occurrence in optics, describing the bright lines seen in a well-lit coffee cup or the dancing networks of light seen at the bottom of a swimming pool on a sunny day. Recently, caustic formation in electron trajectories was identified as the mechanism driving strong current modulations in accelerated charged-particle beams. [...]
