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.

Concepts and Considerations for FCC-ee Top-Up Injection Strategies
/ Ramjiawan, Rebecca (CERN) ; Aiba, Masamitsu (PSI, Villigen) ; Bartmann, Wolfgang (CERN) ; Dutheil, Yann (CERN) ; Hofer, Michael (CERN) ; Hunchak, Patrick (PSI, Villigen)
The Future Circular electron-positron Collider (FCC-ee) is proposed to operate in four modes, with beam energies from 45.6 GeV (Z-pole) to 182.5 GeV (tt-bar production) and luminosities up to 4.6×10³⁶ cm²s⁻¹. At the highest energies the beam lifetime would be less than one hour, meaning that top-up injection will be crucial to maximise the integrated luminosity. [...]

Studies on Top-Up Injection into the FCC-ee Collider Ring

In order to maximize the luminosity production time in the FCC-ee, top-up injection will be employed. The positron and electron beams will be accelerated to the collision energy in the booster ring before being injected with either a small transverse or longitudinal separation to the stored beam.

Top-up injection schemes for future circular lepton collider
/ Aiba, M (PSI, Villigen) ; Goddard, B (CERN) ; Oide, K (CERN ; KEK, Tsukuba) ; Papaphilippou, Y (CERN) ; Saá Hernández, Á (PSI, Villigen) ; Shwartz, D (Novosibirsk, IYF) ; White, S (ESRF, Grenoble) ; Zimmermann, F (CERN)
Top-up injection is an essential ingredient for the future circular lepton collider (FCC-ee) to maximize the integrated luminosity and it determines the design performance. In ttbar operation mode, with a beam energy of 175 GeV, the design lifetime of ∼ 1 h is the shortest of the four anticipated operational modes, and the beam lifetime may be even shorter in actual operation.

In April 2021, scientists active in muon physics met to discuss and work out the physics case for the new High-Intensity Muon Beams (HIMB) project at PSI that could deliver of order $10^{10}$ s$^{-1}$ surface muons to experiments. [...]

Overall Injection Strategy for FCC-ee
/ Ogur, Salim (CERN) ; Aiba, Masamitsu (PSI, Villigen) ; Antoniou, Fanouria (CERN) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Chaikovska, Iryna (Orsay, LAL) ; Charles, Tessa (CERN) ; Chehab, Robert (Orsay, LAL) ; Etisken, Ozgur (Ankara U.) ; Furukawa, Kazuro (KEK, Tsukuba) ; Härer, Bastian (CERN) et al.
The Future Circular electron-positron Collider (FCC-ee) requires fast cycling injectors with very low extraction emittances to provide and maintain extreme luminosities at center of mass energy varying between 91.2-385 GeV in the collider. For this reason, the whole injector complex table is prepared by putting into consideration the minimum fill time from scratch, bootstrapping, transmission efficiency as well as store time of the beams in synchrotrons to approach equilibrium emittances.

Systematic optics studies for the commissioning of the AWAKE electron beamline
/ Bracco, Chiara (CERN) ; Aiba, Masamitsu (PSI, Villigen) ; Goddard, Brennan (CERN) ; Gorgisyan, Ishkhan (CERN) ; Turner, Marlene (CERN) ; Velotti, Francesco (CERN) ; Verra, Livio (CERN)
The commissioning of the AWAKE electron beam line was successfully completed in 2018. Despite a modest length of about 15 m, this low-energy line is quite complex and several iterations were needed before finding satisfactory agreement between the model and the measurements. [...]
