A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

Inst.) ; Arsenyev, Sergey (CERN) ; Barranco, Javier (Ecole Polytechnique, Lausanne) ; Benedikt, Michael (CERN) ; Bruce, Roderik (CERN) et al.
We present updated design parameters for a future High-Energy LHC. A more realistic turnaround time has led to a revision of the target peak luminosity, as well as a choice of a larger IP beta function, and longer physics fills. [...]

Building the impedance model of a real machine
/ Salvant, Benoit (CERN) ; Amorim, David (CERN ; Grenoble, INP) ; Antipov, Sergey (CERN) ; Arsenyev, Sergey (CERN) ; Beck, Mario (CERN) ; Biancacci, Nicolo (CERN) ; Brüning, Oliver (CERN) ; Campelo, Jose Enrique (CERN) ; Carideo, Emanuela (CERN) ; Caspers, Fritz (CERN) et al.
A reliable impedance model of a particle accelerator can be built by combining the beam coupling impedances of all the components. This is a necessary step to be able to evaluate the machine performance limitations, identify the main contributors in case an impedance reduction is required, and study the interaction with other mechanisms such as optics nonlinearities, transverse damper, noise, space charge, electron cloud, beam-beam (in a collider).
