Probing LHC halo dynamics using collimator loss rates at 6.5 TeV / Gorzawski, A (CERN ; Malta U.) ; Appleby, R B (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Giovannozzi, M (CERN) ; Mereghetti, A (CERN) ; Mirarchi, D (CERN) ; Redaelli, S (CERN) ; Salvachua, B (CERN) ; Stancari, G (Fermilab) ; Valentino, G (Malta U.) ; Wagner, J F (CERN ; CERN ; Frankfurt U.)
Halo diffusion measurements at the CERN Large Hadron Collider (LHC) were conducted with beams for physics at 6.5 TeV by means of collimator scans, carried out between 2016 and 2018. From the time evolution of the beam losses recorded during a collimator scan, in which collimator jaws are moved in steps toward the beam core cutting beam tails, one can extract information on the halo diffusion and its population as a function of the transverse amplitude.

Hollow Electron Beam Collimation For HL-LHC - Effect On The Beam Core / Fitterer, M (Fermilab) ; Stancari, G (Fermilab) ; Valishev, A (Fermilab) ; Bruce, R (CERN) ; Papadopoulou, S (CERN) ; Papotti, G (CERN) ; Pellegrini, D (CERN) ; Redaelli, S (CERN) ; Valuch, D (CERN) ; Wagner, J F (CERN)
Collimation with hollow electron beams or lenses (HEL) is currently one of the most promising concepts for active halo control in HL-LHC. In previous studies it has been shown that the halo can be efficiently removed with a hollow electron lens. [...]

Implementation of Hollow Electron Lenses in SixTrack and First Simulation Results for the HL-LHC / Fitterer, M (Fermilab) ; Stancari, G (Fermilab) ; Valishev, a (Fermilab) ; De Maria, R (CERN) ; Redaelli, S (CERN) ; Sjobak, K (CERN) ; Wagner, J F (CERN ; Goethe U., Frankfurt (main))
Electron lenses have found a wide range of applications for hadron colliders, where the main applications are machine protection and beam-beam compensation. This paper summarizes the status of the current electron lens implementation in SixTrack with the focus on hollow electron beams for beam collimation and shows some first simulation results of the High-Luminosity upgrade of the LHC (HL-LHC)..
