A New RadMon Version for the LHC and its Injection Lines / Spiezia, G (CERN) ; Peronnard, P (CERN) ; Masi, A (CERN) ; Brugger, M (CERN) ; Brucoli, M (CERN) ; Danzeca, S (CERN ; CEM2, Montpellier) ; Garcia Alia, R (CERN ; CEM2, Montpellier) ; Losito, R (CERN) ; Mekki, J (CERN) ; Oser, P (CERN) et al.
A system to monitor the radiation levels is required in the Large Hadron Collider (LHC) and its injection lines in order to quantify the radiation effects on electronics. Thus, the RadMons were installed in critical areas where equipment is or will be placed. [...]

Simulator for beam-based LHC collimator alignment / Valentino, Gianluca (CERN ; Malta U.) ; Aßmann, Ralph (DESY) ; Redaelli, Stefano (CERN) ; Sammut, Nicholas (Malta U.)
In the CERN Large Hadron Collider, collimators need to be set up to form a multistage hierarchy to ensure efficient multiturn cleaning of halo particles. Automatic algorithms were introduced during the first run to reduce the beam time required for beam-based setup, improve the alignment accuracy, and reduce the risk of human errors. [...]

Prototype Adjustable Permanent Magnet Quadrupoles For CLIC / Shepherd, Ben J A (Daresbury) ; Clarke, James (Daresbury) ; Bartalesi, Antonio (CERN) ; Modena, Michele (CERN) ; Struik, Michael (CERN) ; Collomb, Norbert (Daresbury)
The 42km long Drive Beam Decelerator for the Compact Linear Collider (CLIC) requires over 41,000 quadrupole magnets. ASTeC and CERN are investigating the possibility of permanent magnet quadrupoles (PMQs) to reduce running costs and heat load inside the CLIC tunnel. [...]

Plasmaphys.) ; Reimann, Olaf (Garching, Max Planck Inst. Plasmaphys.) ; Lotov, Konstantin (Novosibirsk, IYF) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf) et al.
The goal of the AWKAKE collaboration is the study of plasma wakefields driven by proton (p⁺) bunches through experiments, simulations and theory. Proton bunches are interesting wakefield drivers because they can be ultra-relativistic (TeVs/p⁺) and carry large amounts of energy (>kJ). [...]

Proton Electron Accelerator at CERN / Tarkeshian, Roxana (Munich, Max Planck Inst.) /AWAKE
AWAKE is a proton driven plasma-wakefield acceleration at CERN*, that uses long proton bunches ~ 400 ps from the SPS. In a dense plasma, a long proton bunch is subject toμbunching at plasma period due to the self-modulation instability, SMI** [...]

Device and Technique for In-situ Coating of the RHIC Cold Bore Vacuum Tubes with Thick OFHC / Hershcovitch, Ady (RIKEN BNL) ; Blaskiewicz, Michael (RIKEN BNL) ; Brennan, Joseph (RIKEN BNL) ; Fischer, Wolfram (RIKEN BNL) ; Liaw, Chong-Jer (RIKEN BNL) ; Meng, Wuzheng (RIKEN BNL) ; Todd, Robert (RIKEN BNL) ; Custer, Art (Unlisted, US) ; Erickson, Mark (Unlisted, US) ; Jamshidi, Nader (Unlisted, US) et al.
To mitigate electron clouds & unacceptable ohmic heating problems in RHIC, we developed a robotic plasma deposition technique & device to in-situ coat the RHIC 316LN SS cold bore tubes based on mobile mole mounted magnetrons for OFHC deposition. Scrubbed Cu has low SEY and suppress electron cloud formation. [...]

Crystal-assisted Collimation Experiment from the SPS to the LHC / Scandale, Walter (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN) /UA9
UA9 was operated in the CERN-SPS for more than six years in view of investigating the feasibility of the halo collimation assisted by bent crystals. Two-millimeter-long silicon crystals, with bending angles of about 150 μrad, are used as primary collimators. [...]

Design of a Magnetic Bump Tail Scraping System for the CERN SPS / Mete, Öznur (CERN) ; Bauche, Jeremie (CERN) ; Cerutti, Francesco (CERN) ; Cettour Cave, Stephane (CERN) ; Cornelis, Karel (CERN) ; Drøsdal, Lene (CERN) ; Galleazzi, Frederic (CERN) ; Goddard, Brennan (CERN) ; Jensen, Lars (CERN) ; Kain, Verena (CERN) et al.
The LHC injectors are being upgraded to meet the demanding beam specification required for High Luminosity LHC (HL-LHC) operation. In order to reduce the beam losses which can trigger the sensitive LHC beam loss interlocks during the SPS-to-LHC beam injection process, it is important that the beam tails are properly scraped away in the SPS.
