The Future Circular Collider study, which aims at designing post-LHC particle accelerator
options, is entering in the final stage, which foresees a conceptual design report containing …

The study of collective effects in circular accelerators can be tackled by solving numerically
the Vlasov equation or by using tracking codes. The two methods are obtained with different …

The Future Circular Collider FCC-ee is a study toward a high luminosity electron-positron
collider with a centre-of-mass energy from 91 GeV to 365 GeV. Due to the beam parameters …

In order to reach high luminosity, the Future Circular e^++ e^--Collider will need very intense
beams with small emittances and small beta functions in the interaction points. This is …

The FCC-ee impedance model is being constantly updated closely following the vacuum
chamber design and parameters evolution. In particular, at present, a thicker NEG coating of …

The simulation of beam dynamics in the presence of collective effects requires a strong
computational effort to take into account, in a self-consistent way, the wakefield acting on a …

The resistive wall impedance of a vacuum chamber with elliptic cross section is of particular
interest for circular particle accelerators as well as for undulators in free electron lasers. By …

A destabilizing effect of the detuning impedance has been recently observed in simulations
of the CERN Proton Synchrotron (PS) at the injection energy: while without the detuning …

The CERN Proton Synchrotron (PS) routinely crosses transition energy at around 6 GeV in
order to accelerate protons that are injected in the Super Proton Synchrotron (SPS) or …

A very important issue for the Future Circular Collider (FCC) is represented by collective
effects due to the selfinduced electromagnetic fields, which, acting back on the beam, could …
