The Future Circular Collider (FCC) ‘integrated programme’ consists of an initial electron-positron collider FCC-ee, which is later followed by a proton-proton collider, FCC-hh, installed in the same 91 km circumference tunnel close to CERN. Over a span of 15 years, from the mid or late 2040s through the early 2060s, the FCC-ee shall operate at centre-of-mass energies between about 90 and 365 GeV, always delivering the highest possible luminosities to four experiments, in a sustainable and energy-efficient way.

The ongoing feasibility study of the Future Circular Collider (FCC) comprises two distinct accelerators: a high-luminosity circular electron-positron collider known as FCC-ee and an energy-frontier hadron collider named FCC-hh. These two facilities are designed to take advantage of a common tunnel infrastructure. [...]

Hybrid on-axis and off-axis top-up injection at the future circular lepton collider
/ Yue, Sen (CERN) ; Dutheil, Yann (CERN) ; Bartmann, Wolfgang (CERN) ; Johnson, Eliott (CERN) ; Martinek, Petr (CERN)
In order to maximize the integrated luminosity of the future circular lepton collider (FCC-ee), a top-up injection scheme is required. Amongst the four operation modes of FCC-ee, the Z operation mode has the highest stored beam energy in the collider ring with about 20 MJ per beam. [...]

The Super Proton Synchrotron (SPS) is the second largest synchrotron at CERN and produces high-brightness beams for the Large Hadron Collider (LHC). Recently, the dilution kicker (MKDH) of the SPS beam dump system (SBDS) has demonstrated unanticipated behaviour under high beam brightness conditions. [...]

FCC-ee $e^+e^-$ Injection and Booster rRng

The Future Circular electron-positron Collider (FCC-ee) is a proposal for a 91.17 km collider, which would operate in four modes with energies ranging from 45.6 GeV (Z-pole) to 182.5 GeV (ttbar-production). At high energies the beam lifetime could be as low as 6 minutes, requiring the beam to be continuously topped up to reach a high integrated luminosity. [...]
