Thermal and Modal Simulations for the CLIC Module / Petry, Alice (Helsinki Institute of Physics (FI))
The accelerating technologies used in CLIC currently have an RF efficiency of about 40 % The RF losses are dissipated as heat into the cavity disks of the super-accelerating structures, which leads to unwanted thermal deformation. [...]

High-energy collisions of hadrons: what are the dynamical mechanisms? / Van Hove, L (CERN)
A survey is given of the two dominant mechanisms which have been recognized to operate in high-energy collisions of hadrons, namely diffraction scattering and reggeized article exchange. The main characteristics of these mechanisms are discussed on the basis of the experimental evidence from two-body processes. [...]

Incoherent electron cloud effects in the Large Hadron Collider / Paraschou, K (CERN ; Aristotle U., Thessaloniki) ; Iadarola, G (CERN)
During the operation of the Large Hadron Collider in 2018, the majority of physics data was collected with a beam energy of 6.5 TeV, a bunch spacing of 25 ns and with β-functions in the high luminosity interaction points equal to 30 cm. In this configuration, it was found through several experimental measurements that electron cloud induces a significant degradation of the beam lifetime. [...]

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. [...]
