The High Luminosity LHC project is now entering in the final stage of design. Aimed at improving the LHC reach in integrated luminosity for 300 to 3000 fb-1, the project relies on a few novelties: 1) use of a special optics, the achromatic telescopic squeeze to enhance beam matching and chromaticity correction beyond the present LHC possibility; use of advanced magnet technology based on Nb3Sn...

We are developing the fast muon kicker for the muon g-2 experiment at Fermilab. The kicker is a pulsed magnet that provides the transverse kick to the muon particles required to direct them onto the stable (magic radius) orbit of the storage ring. To provide the right kick and maximize the storage efficiency of muons, the magnetic pulse generated from the kicker should have ,approximately, 250...

Interaction point (IP) beam parameters at future linear colliders have been chosen in order to limit the impact of non-linear effects from strong electromagnetic fields at the IP. However the field strength experienced by incoming particles is still a significant percentage of the field strength that polarises the vacuum. These vacuum changes can be taken into account at Lagrangian level via...
