Design, Fabrication and Tests of the Second Prototype of the Double-Length CLIC PETS / Sánchez, Laura (Madrid, CIEMAT) ; Calero, Jesus (Madrid, CIEMAT) ; Gavela, Daniel (Madrid, CIEMAT) ; Gutiérrez, Jose Luis (Madrid, CIEMAT) ; Toral, Fernando (Madrid, CIEMAT) ; Gudkov, Dmitry (CERN) ; Riddone, Germana (CERN)
The future collider CLIC is based on a two-beam acceleration scheme, where the drive beam provides to the main beam the RF power through the Power Extraction and Transfer Structures (PETS). The technical feasibility of some components is currently being proved at the CLIC Experimental Area (CLEX). [...]

HL-LHC Performance with a 200 MHz RF System / Tomás, Rogelio (CERN) ; Domínguez, César (CERN) ; White, Simon (CERN)
The HL-LHC performance could considerably benefit from having a 200 MHz RF system. This would allow to inject longer bunches with larger bunch intensity from the SPS and to perform bunch length leveling if required. [...]

Feasibility Studies for 100 GeV Beam Transfer Lines for a CERN Neutrino Facility / Kowalska, Magdalena (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Goddard, Brennan (CERN) ; Nessi, Marzio (CERN) ; Steerenberg, Rende (CERN) ; Velotti, Francesco M (CERN)
For a potential future CERN neutrino facility it is considered to extract a 100 GeV proton beam from the second long straight section in the SPS into the existing TT20 transfer line leading to the North Area. Two transfer line design options were developed simultaneously: early-branching from TT20 using existing, recuperated ‘experimental area’ DC dipoles and alternatively late-branching close to the target area, which requires superconducting magnets.

Design Studies of the Upgraded Collimation System in the SPS-to-LHC Transfer Lines / Mereghetti, Alessio (CERN) ; Bracco, Chiara (CERN) ; Cerutti, Francesco (CERN) ; Goddard, Brennan (CERN) ; Hrivnak, Jan (CERN) ; Kain, Verena (CERN) ; Maciariello, Fausto L (CERN) ; Meddahi, Malika (CERN) ; Steele, Genevieve E (CERN) ; Appleby, Robert (Unlisted, UK)
In the framework of the LHC Injectors Upgrade (LIU) Project, the collimators in the SPS-to-LHC transfer lines are presently under re-design, in order to cope with the unprecedented beam intensities and emittances required by the High Luminosity LHC (HL-LHC). Factors ruling the design phase are the robustness of the jaws on one side and, on the other side, the proton absorption and the emittance blow-up, essential for an effective protection of the equipment in the LHC injection regions and the LHC machine.

Comparison of the Results of a Hydrodynamic Tunneling Experiment with Iterative FLUKA and BIG2 Simulations / Burkart, Florian (CERN) ; Blanco, Juan (CERN) ; Grenier, Damien (CERN) ; Schmidt, Ruediger (CERN) ; Wollmann, Daniel (CERN) ; Tahir, Naeem (Darmstadt, GSI)
In 2012, a novel experiment has been performed at the CERN HiRadMat facility to study the impact of a 440 GeV proton beam generated by the Super Proton Synchrotron (SPS), on extended solid copper cylindrical targets. Substantial hydrodynamic tunneling of the protons in the target material has been observed. [...]

Cleaning Performance with 11T Dipoles and Local Dispersion Suppressor Collimation at the LHC / Bruce, Roderik (CERN) ; Marsili, Aurelien (CERN) ; Redaelli, Stefano (CERN)
The limiting location of the present LHC machine in terms of losses on cold magnets are the dispersion suppressors downstream of the betatron collimation insertion (IR7). These losses are dominated by off-energy protons that have by-passed the upstream secondary collimation system but are lost where the dispersion starts to rise. [...]

Key Design Features of Crab-Cavity Cryomodule for HiLumi LHC / Pattalwar, Shrikant (Daresbury) ; May, Andrew J (Daresbury) ; McIntosh, Peter A (Daresbury) ; Wheelhouse, Alan E (Daresbury) ; Burt, Graeme (Lancaster U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Hall, Benjamin (Lancaster U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Capatina, Ofelia (CERN) ; Jones, Thomas (Daresbury) ; Templeton, Niklas (Daresbury) ; Nicol, Thomas (Fermilab)
A prototype Superconducting RF (SRF) cryomodule, comprising multiple compact crab cavities is foreseen to realise a local crab crossing scheme for the “Hi-Lumi LHC”, a project launched by CERN to increase the luminosity performance of LHC. A cryomodule with two cavities will be initially installed and tested on the SPS drive accelerator at CERN to evaluate performance with high-intensity proton beams. [...]

Recent Results from CTF3 Two Beam Test Stand / Farabolini, Wilfrid (IRFU, Saclay ; CEA, DSM, Saclay) ; Peauger, Franck (IRFU, Saclay ; CEA, DSM, Saclay) ; Borgmann, Christopher (Uppsala U.) ; Ögren, Jim (Uppsala U.) ; Ruber, Roger (Uppsala U.) ; Corsini, Roberto (CERN) ; Gamba, Davide (CERN) ; Grudiev, Alexej (CERN) ; Khan, Muhammad Asif (CERN) ; Mazzoni, Stefano (CERN) et al.
From mid-2012, the Two Beam Test Stand (TBTS) in the CTF3 Experimental Facility is hosting 2 high gradient accelerating structures powered by a single power extraction and transfer structure in a scheme very close to the CLIC basic cell. We report here about the results obtained with this configuration as: energy gain and energy spread in relation with RF phases and power, octupolar transverse beam effects compared with modeling predictions, breakdown rate and breakdown locations within the structures.

Determination of the Magnetic Axis of a CLIC Drive Beam Quadrupole with respect to External Alignment Targets using a Combination of WPS, CMM and Laser Tracker Measurements / Duquenne, Mathieu (CERN) ; Anastasopoulos, Michail (CERN) ; Caiazza, Domenico (CERN) ; Deferne, Guy (CERN) ; Garcia Perez, Juan (CERN) ; Mainaud Durand, Helene (CERN) ; Modena, Michele (CERN) ; Rude, Vivien (CERN) ; Sandomierski, Jacek (CERN) ; Sosin, Mateusz (CERN)
CERN is currently studying the feasibility of building a high energy e⁺ e^{−} linear collider: the CLIC (Compact LInear Collider). One of the engineering challenges is the pre-alignment precision and accuracy requirement on the alignment of the linac components. [...]
