Realization and First Test Results of the EuCARD 5.4-T REBCO Dipole Magnet / Durante, Maria ; Borgnolutti, Franck ; Bouziat, Denis ; Fazilleau, Philippe ; Gheller, Jean-Marc ; Molinie, Frederic ; De Antoni, Philippe
Abstract: A high-temperature critical superconductor (HTS) dipole magnet relying on 12-mm REBCO tapes was built at CEA Saclay in 2016. Magnet studies had been started in the framework of the EuCARD High Field Magnet program and continued within a collaboration agreement between CEA-Saclay and CERN. [...]

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.
