Machine Induced Backgrounds in the FCC-ee MDI Region and Beamstrahlung Radiation
/ Ciarma, Andrea (CERN) ; Boscolo, Manuela (Frascati) ; Ganis, Gerardo (CERN) ; Perez, Emmanuelle (CERN)
The new design for the central chamber of the FCC-ee beam pipe has a reduced radius of R=10mm and length of L=18cm, allowing to have the inner layer of the Vertex Detector Barrel closer to the interaction point. The effect of the background induced occupancy due to Incoherent Pairs Creation (IPC), beam losses in the MDI area and Synchrotron Radiation are explored for the CLD detector, using the updated version of the Vertex Detector for the new central beam pipe.

The Future Circular Collider electron-positron (FCC-ee) is a proposed high-energy lepton collider that aims to reach unprecedented precision in the measurements of fundamental particles. Several beam related processes produce particles in the Machine-Detector Interface (MDI) region, which can adversely affect the measurements’ accuracy. [...]

Mitigation of the impedance-related collective effects in FCC-ee
/ Zobov, Mikhail (Frascati) ; Belli, E (CERN) ; Kersevan, Roberto (CERN) ; Novokhatski, A (SLAC) ; Zadeh, S G (Rostock U.) ; Migliorati, Mauro (Rome U.)
In order to achieve a high luminosity in the electron-positron Future Circular Collider (FCC-ee), very intense multi-bunch beams with low emittances are accumulated in two separate rings and collide in two interaction regions exploiting the crab waist collision scheme. In order to preserve beam quality and to avoid collider performance degradation a careful study of beam collective effects is required. [...]

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.
