Mitigation of electron cloud effects in the FCC-ee collider [PDF]
EPJ Techniques and Instrumentation, 2022 Electron clouds forming inside the beam vacuum chamber due to photoemission and secondary emission may limit the accelerator performance. Specifically, the electron clouds can blow up the vertical emittance of a positron beam, through a head-tail-type ...

The FCC-ee vacuum system, from conceptual to prototyping [PDF]
EPJ Techniques and Instrumentation, 2022 The FCC-ee is a very challenging accelerator project from the point of view of vacuum. Apart from the sheer size of the machine, a twin-ring of 100 km circumference, the vacuum system design must be capable of dealing with the low-energy 45.6 GeV, high ...

QED challenges at FCC-ee precision measurements
European Physical Journal C: Particles and Fields, 2019 The expected experimental precision of the rates and asymmetries in the Future Circular Collider with electron–positron beams (FCC-ee) in the center of the mass energy range 88–365 GeV considered for construction in CERN, will be better by a factor 5–200.

FCC-ee accelerator parameters, performance and limitations
, 2016 CERN has recently launched the Future Circular Collider (FCC) study to deal with all aspects of an ambitious post-LHC possible programme. The emphasis of the study is on a 100 TeV proton collider to be housed in a 80-100 km new ring in the Geneva region.
