Electron cloud buildup studies for the LHC / Dijkstal, Philipp (Technische Universitaet Darmstadt (DE)) ; Iadarola, Giovanni (dir.) (CERN) ; Boine-Frankenheim, Oliver (dir.) (TU Darmstadt)
Electron clouds can develop in accelerators operating with positively charged particles. The con- sequences of e-cloud related effects are very important for the operation of the Large Hadron Collider (LHC) at CERN, and for the design of future accelerators including the LHC luminosity upgrade (HL-LHC) [...]

Design of a compact superconducting crab-cavity for LHC using Nb-on-Cu-coating technique / Grudiev, Alexej (CERN) ; Atieh, Said (CERN) ; Calaga, Rama (CERN) ; Calatroni, Sergio (CERN) ; Capatina, Ofelia (CERN) ; Carra, Federico (CERN) ; Favre, Gilles (CERN) ; Ferreira, Leonel (CERN) ; Poncet, Jean-Francois (CERN) ; Richard, Thibaut (CERN) et al.
The design of a compact superconducting crab-cavity for LHC using Nb-on-Cu-coating technique is presented. The cavity shape is based on the ridged waveguide resonator with wide open apertures to provide access to the inner surface of the cavity for coating. [...]

Beam Tests of a Single-Channel Bunch-Crossing Identification Module for the Level-1 Trigger / Brawn, I P (Birmingham U.) ; Carney, R E (Birmingham U.) ; Ermolin, Y (Birmingham U.) ; Garvey, J (Birmingham U.) ; Staley, R J (Birmingham U.) ; Watson, A T (Birmingham U.) ; Eisenhandler, E (Queen Mary, U. of London) ; Landon, M (Queen Mary, U. of London) ; Gee, C N P (Rutherford) ; Gillman, A R (Rutherford) et al. /RD27
Identifying a pulse which spans several sampling periods with only one of those sampling periods is a non-trivial problem which must be addressed in the context of level-1 triggering for the LHC. We have built and tested a single-channel bunch-crossing identification demonstrator which implements digital algorithms to extract such timing information..

Design and implementation of a crystal collimation test stand at the Large Hadron Collider / Mirarchi, Daniele (CERN) ; Hall, G (Imperial Coll., London) ; Redaelli, S (CERN) ; Scandale, W (CERN)
Future upgrades of the CERN Large Hadron Collider (LHC) demand improved cleaning performance of its collimation system. Very efficient collimation is required during regular operations at high intensities, because even a small amount of energy deposited on superconducting magnets can cause an abrupt loss of superconducting conditions (quench).
