Simulations in Support of Wire Beam-Beam Compensation Experiment at the LHC / Patapenka, Andrei (NIU, DeKalb ; Fermilab) ; Papaphilippou, Yannis (CERN) ; De Maria, Riccardo (CERN) ; Valishev, Alexander (Fermilab)
The compensation of long-range beam-beam interaction with current wires is considered as a possible technology for the HL-LHC upgrade project. A demonstration experiment is planned in the present LHC machine starting in 2018. [...]

Impedance and Thermal Studies of the LHC Injection Kicker Magnet Upgrade / Barnes, Michael J (CERN) ; Bjorkqvist, Oskar (CERN) ; Motschmann, Fritz (CERN)
The bunch intensities of High Luminosity (HL) LHC are predicted to lead to heating of the ferrite yokes of the LHC injection kicker magnets (MKI), in their current configuration, to their Curie temperature. Hence, the MKIs are being upgraded to meet the requirements of HL-LHC, which is planned to start in the mid-2020s. [...]

Modelling the experimental data for long-range beam-beam wire compensators at the CERN LHC with diffusive models / Montanari, C E (Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giovannozzi, M (CERN) ; Poyet, A (CERN) ; Sterbini, G (CERN)
Current-carrying wires have long been proposed as measures to mitigate beam-beam effects. Dedicated hardware has been installed at CERN Large Hadron Collider (LHC) and experimental sessions have been organised to study the beam dynamics in the presence of the wire compensators. [...]

Dynamic Testing and Characterization of Advanced Materials in a New Experiment at CERN HiRadMat Facility / Bertarelli, Alessandro (CERN) ; Accettura, Carlotta (CERN ; Milan Polytechnic) ; Berthomé, Emmanuel (CERN) ; Bianchi, Laura (CERN) ; Bolz, Philipp (Darmstadt, GSI) ; Carra, Federico (CERN) ; Fichera, Claudio (CERN) ; Frankl, Matthias (CERN) ; Furness, Thomas (Huddersfield U.) ; Gobbi, Giorgia (CERN) et al.
An innovative and comprehensive experiment (named “Multimat”) was successfully carried out at CERN HiRadMat facility on 18 different materials relevant for Collimators and Beam Intercepting Devices. Material samples, tested under high intensity proton pulses of 440 GeV/c, exceeding the energy density expected in HL-LHC, ranged from very light carbon foams to tungsten heavy alloys, including novel composites as graphite/carbides and metal/diamond without and with thin-film coatings.

Potential and constraints of a beam-beam wire compensator in the HL-LHC era / Sterbini, G (CERN) ; Bertarelli, A (CERN) ; Papaphilippou, Y (CERN) ; Poyet, A (CERN) ; Rossi, A (CERN) ; Bélanger, P (TRIUMF)
The compensation of the long-range beam-beam interactions by DC wires is currently being investigated as an option for enhancing machine performance in the framework of the High-Luminosity LHC Project. In this paper, we report and comment on the potential of wire compensation during the first HL-LHC run. [...]
