Test-driven software upgrade of the LHC beam-based feedback systems / Alves, Diogo (CERN) ; Fuchsberger, Kajetan (CERN) ; Jackson, Stephen (CERN) ; Wenninger, Jorg (CERN)
The beam-based feedback system is essential for the operation of the LHC. It comprises two C++ servers: a FESA-based (framework for real-time systems developed at CERN) acquisition and configuration proxy, and a non FESA-based controller which sanitises the acquisition data and feeds it to multiple real-time feedback algorithms (orbit control, radialloop control and tune control) ensuring a stable orbit of the LHC's beams. [...]

Manipulation of hadron beams with bent crystals in circular accelerators / Rossi, R (CERN ; INFN, Rome) ; Cavoto, G (INFN, Rome) ; Redaelli, S (CERN) ; Scandale, W (CERN) /UA9
Over the past years the understanding and use of coherent interactions of charged particles with ordered crystal lattices has achieved excellent results. Improving collimation of hadron beams in circular accelerators, like the Large Hadron Collider (LHC) of the European Council for Nuclear Research (CERN), it is one of the possible applications. [...]

High Frequency Electro-Optic Beam Position Monitors for Intra-Bunch Diagnostics at the LHC / Gibson, Stephen (Royal Holloway, U. of London) ; Arteche, Alberto (Royal Holloway, U. of London) ; Boorman, Gary (Royal Holloway, U. of London) ; Bosco, Alessio (Royal Holloway, U. of London) ; Darmedru, Pierre-Yves (CERN) ; Lefèvre, Thibaut (CERN) ; Levens, Thomas (CERN)
At the HL-LHC, proton bunches will be rotated by crab-cavities close to the interaction regions to maximize the luminosity. A method to rapidly monitor the transverse position of particles within each 1ns bunch is required. [...]
