Single Bunch Instabilities in FCC-ee
/ Belli, Eleonora (CERN) ; Castorina, Giovanni (INFN, Rome) ; Migliorati, Mauro (INFN, Rome) ; Rumolo, Giovanni (CERN) ; Spataro, Bruno (Frascati) ; Zobov, Mikhail (Frascati)
FCC-ee is a high luminosity lepton collider with a centre-of-mass energy from 91 to 365 GeV. Due to the machine parameters and pipe dimensions, collective effects due to electromagnetic fields produced by the interaction of the beam with the vacuum chamber can be one of the main limitations to the machine performance. [...]

Rome La Sapienza (main) ; INFN, Rome) ; Migliorati, M (U. Rome La Sapienza (main) ; INFN, Rome)
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 and pipe dimensions, collective effects and electron cloud can be very critical aspects for the machine and can represent the main limitations to its performance. [...]

Study of Collective Effects in the FCC-ee Collider
/ Zobov, Mikhail (Frascati) ; Belli, Eleonora (CERN ; Rome U. ; INFN, Rome) ; Castorina, Giovanni (Rome U. ; INFN, Rome) ; Migliorati, Mauro (Rome U. ; INFN, Rome) ; Persichelli, Serena (LBNL, Berkeley) ; Rumolo, Giovanni (CERN) ; Spataro, Bruno (Frascati)
The Future Circular Collider (FCC) study aims at designing different options of a post-LHC collider. The high luminosity electron-positron collider FCC-ee based on the crab waist concept is considered as an intermediate step on the way towards FCC-hh, a 100 TeV hadron collider using the same tunnel of about 100 km.

Coupling Impedances and Collective Effects for FCC-ee
/ Belli, Eleonora (U. Rome La Sapienza (main)) ; Castorina, Giovanni (Frascati) ; Migliorati, Mauro (Rome U.) ; Novokhatski, Alexander (SLAC) ; Persichelli, Serena (LBNL, Berkeley) ; Spataro, Bruno (Frascati) ; Zobov, Mikhail (Frascati)
A very important issue for the Future Circular Collider (FCC) is represented by collective effects due to the self-induced electromagnetic fields, which, acting back on the beam, could produce dangerous instabilities. In this paper we will focus our work on the FCC electron-positron machine: in particular we will study some important sources of wake fields, their coupling impedances and the impact on the beam dynamics.

Collective Effects Issues for FCC-ee
/ Migliorati, M (U. Rome La Sapienza (main) ; INFN, Rome) ; Belli, E (U. Rome La Sapienza (main) ; INFN, Rome ; CERN) ; Castorina, G (Frascati) ; Persichelli, S (LBNL, Berkeley) ; Spataro, B (Frascati) ; Zobov, M (Frascati)
The Future Circular Collider study, hosted by CERN to design post-LHC particle accelerator options in a worldwide context, represents a great challenge under several aspects, which require R&D; on beam dynamics and new technologies. One very critical point is represented by collective effects, generated by the interaction of the beam with self-induced electromagnetic fields, called wake fields, which could produce beam instabilities, thus reducing the machines performance and limiting the maximum stored current.

EuPRAXIA@SPARC_LAB Design study towards a compact FEL facility at LNF
/ Ferrario, M. (Frascati) ; Alesini, D. (Frascati) ; Anania, M.P. (Frascati) ; Artioli, M. (ENEA, Bologna) ; Bacci, A. (INFN, Milan) ; Bartocci, S. (Sassari U.) ; Bedogni, R. (Frascati) ; Bellaveglia, M. (Frascati) ; Biagioni, A. (Frascati) ; Bisesto, F. (Frascati) et al.
On the wake of the results obtained so far at the SPARC\_LAB test-facility at the Laboratori Nazionali di Frascati (Italy), we are currently investigating the possibility to design and build a new multi-disciplinary user-facility, equipped with a soft X-ray Free Electron Laser (FEL) driven by a $\sim$1 GeV high brightness linac based on plasma accelerator modules. This design study is performed in synergy with the EuPRAXIA design study. [...]

Some Critical Collective Effects for the FCC-ee Collider
/ Belli, Eleonora (CERN) ; Castorina, Giovanni (U. Rome La Sapienza (main)) ; Migliorati, Mauro (U. Rome La Sapienza (main)) ; Persichelli, Serena (LBL, Berkeley) ; Rumolo, Giovanni (CERN) ; Spataro, Bruno (Frascati) ; Zobov, Mikhail (Frascati)
In the framework of the Future Circular Collider (FCC) design studies at CERN [1], the high luminosity electron-positron collider FCC-ee is considered as a possible first step towards FCC-hh, a 100 TeV hadron collider in the same tunnel of about 100 km. Table 1 summarizes the main beam parameters at four different center-of-mass energies from 45.6 GeV (Z pole) to 175 GeV (top pair threshold). [...]

Femtosecond timing-jitter between photo-cathode laser and ultra-short electron bunches by means of hybrid compression
/ Pompili, Riccardo (Laboratory Nazionali di Frascati) ; Anania, M.P (Laboratory Nazionali di Frascati) ; Bellaveglia, M (Laboratory Nazionali di Frascati) ; Biagioni, A (Laboratory Nazionali di Frascati) ; Castorina, G (Laboratory Nazionali di Frascati and University of Catania) ; Chiadroni, E (Laboratory Nazionali di Frascati) ; Cianchi, A (University of Rome Tor Vergata) ; Croia, M (Laboratory Nazionali di Frascati) ; Di Giovenale, D (Laboratory Nazionali di Frascati) ; Ferrario, M (Laboratory Nazionali di Frascati) et al.
The generation of ultra-short electron bunches with ultra-low timing-jitter relative to the photo-cathode (PC) laser has been experimentally proved for the first time at the SPARC_LAB test-facility (INFN-LNF, Frascati) exploiting a two-stage hybrid compression scheme. The first stage employs RF-based compression (velocity-bunching), which shortens the bunch and imprints an energy chirp on it. [...]
