 Emittance reduction with variable bending magnet strengths: Analytical optics considerations / Papadopoulou, S. (CERN ; Crete U. ; Crete, Tech. U.) ; Antoniou, F. (CERN) ; Papaphilippou, Y. (CERN) One of the main challenges of the lattice design of $e^+e^{{-}}$ synchrotrons, used as light sources or damping rings, is the minimization of the emittance.

 Design Development for the Beam Dump Facility Target Complex at CERN / Kershaw, K. (CERN) ; Grenard, J.-L (CERN) ; Calviani, M. (CERN) ; Ahdida, C. (CERN) ; Casolino, M. (CERN) ; Delavalle, S. (LeCroy, Oxford) ; Hounsome, D. (LeCroy, Oxford) ; Jacobsson, R. (CERN) ; Lamont, M. (CERN) ; Lopez Sola, E. (CERN) et al. CERN has launched a study phase to evaluate the feasibility of a new high-intensity beam dump facility at the CERN Super Proton Synchrotron accelerator with the primary goal of exploring Hidden Sector models and searching for Light Dark Matter, but which also offers opportunities for other fixed target flavour physics programs such as rare tau lepton decays and tau neutrino studies.

 Hit multiplicity approach to b-tagging in FCC-hh / Perez Codina, Estel (CERN) ; Roloff, Philipp Gerhard (CERN) The FCC-hh project aims to study proton-proton collisions at $\sqrt{s}$=100 TeV. The ability to tag heavy flavour jets of high energy produced in those collisions will be crucial for many beyond the Standard Model searches such as Z' production.

 Future Circular Collider Study (FCC) / Golling, Tobias (Geneva U.) The status and plans for the Future Circular Collider (FCC) design study are presented. The ultimate goal, and the emphasis for the infrastructure, is a proton-proton machine operating at a center-of-mass energy of 100 TeV in a 100-km ring in the Geneva area, called FCC-hh.

 N-doped surfaces of superconducting niobium cavities as a disordered composite / Weingarten, Wolfgang (CERN) The Q-factor of superconducting accelerating cavities can be substantially improved by a special heat treatment under N2 atmosphere (N-doping). Recent experiments at Fermi National Laboratory investigated the dependence of Q on the RF frequency and showed, unexpectedly, both an increase and a decrease with the RF field amplitude.
