The effects of an electron cloud (e-cloud) on beam dynamics are one of the major factors limiting performances of high intensity positron, proton, and ion storage rings. In the electron-positron collider DAΦNE, namely, a horizontal beam instability due to the electron-cloud effect has been identified as one of the main limitations on the maximum stored positron beam current and as a source of beam quality deterioration.

Recently the DAФNE electron-positron collider has started delivering luminosity to the KLOE-2 experiment. For this run special metallic electrodes were installed in all the dipole and wiggler magnets of the positron ring to cope with the effects induced by the e-cloud formation. [...]

During the current run of an electron-positron collider DAFNE special electrodes for electron cloud suppression have been inserted in all dipole and wiggler magnets of the positron ring. In this paper we discuss the impact of these electrodes on beam dynamics and overall collider performance. [...]

Electron cloud build-up study for DAPHNE
/ Vaccarezza, C ; Cimino, R ; Bellodi, G ; Drago, A ; Ohmi, K ; Pivi, M ; Rumolo, Giovanni ; Schulte, Daniel ; Zimmermann, Frank ; Zobov, M
After the first experimental observations compatible with the presence of the electron cloud effect in the DAFNE positron ring, a more systematic study has been performed regarding the e-cloud build-up and related instability. The measured field map of the magnetic field has been taken into account in the simulation for elements present in the four 10 m long bending sections, representing 40% of the whole positron ring.

Electron cloud build-up studies for FCC-ee
/ Sabato, L (Ecole Polytechnique, Lausanne) ; Pieloni, T (Ecole Polytechnique, Lausanne) ; Iadarola, G (CERN) ; Mether, L (CERN)
The Future Circular Collider (FCC) study is developing designs for a new research infrastructure to host the next generation of higher performance particle colliders to extend the research currently being conducted at CERN. In particular, FCC-ee is an electron-positron collider, which is the first stage towards a 100 TeV proton-proton collider FCC-hh.FCC-ee may be affected by electron cloud (e-cloud) and the strongest effects are foreseen for the Z configuration, due to the highest number of bunches, which corresponds to the smallest bunch spacing.

Single beam collective effects in FCC-ee due to beam coupling impedance
/ Belli, Eleonora (Universita e INFN, Roma I (IT)) ; Migliorati, Mauro (Universita e INFN, Roma I (IT)) ; Persichelli, Serena ; Zobov, Mikhail
The Future Circular Collider study, hosted by CERN to design post-LHC particle accelerator options in a worldwide context, is focused on proton-proton high-energy and electron-positron high-luminosity frontier machines. This new accelerator complex represents a great challenge under several aspects, which involve R&D; on beam dynamics and new technologies. [...]
