LHC injection losses for tighter collimator settings in view of HE-LHC / Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Bruce, Roderik (CERN) ; Crouch, Matthew Paul ; Goddard, Brennan (CERN) ; Molson, James (CERN) ; Redaelli, Stefano (CERN)
In view of the smaller physical apertures of Nb3Sn magnets for the HE-LHC study, a machine study was performed in the LHC to tighten correspondingly the ring and injection protection collimators and measure the change in loss behaviour. [...]

Systematic error studies for the charged particle EDM measurement proposal / Tahar, M. Haj (CERN) ; Carli, C. (CERN)
Proposals aimed at measuring the Electric Dipole Moment (EDM) for charged particles require a good understanding of the systematic errors that can contribute to a vertical spin buildup mimicking the EDM signal to be detected. [...]
