Optimisation analysis and improvement of the effective beam sizes in Accelerator Test Facility 2 / Patecki, Marcin (Warsaw University of Technology (PL)) ; Tomàs, Rogelio (dir.) (CERN) ; Kisiel, Adam (dir.) (Warsaw University of Technology)
A lepton linear collider is considered by the accelerator and particle physics communities as an appropriate machine to perform high precision particle physics research in the TeV energy regime. There are two proposals for the future e+e- linear collider: the Compact Linear Collider (CLIC) and the International Linear Collider (ILC), both developed by two wide international collaborations with strong overlap between them.

Early-stage fault isolation based on frequency response fitted by small-size samples for cryogenic cold compressors with active magnetic bearings / Arpaia, Pasquale (Naples U. ; CERN) ; De Vito, Luca (Sannio U. ; CERN) ; Girone, Mario (Sannio U.) ; Pezzetti, Marco (CERN)
A model-based method for fault detection and early-stage isolation, applicable when unfaulty conditions can be identified only by a reduced number of trials (even only one), is presented. The basic idea is to model analytically the uncertainty of the unfaulty frequency response and express the fault condition in terms of the noise power variance. [...]

Establishing a Consistent Basis for Beam Physics, Accelerator Magnet Design, and Magnetic Measurements / Russenschuck, Stephan (CERN)
The paper describes the recent efforts in establishing a consistent basis for beam physics simulations and machine requirements, magnet design and manufacture, and magnetic measurements. Magnetic field measurements serve for the quality assurance of the magnet production, and for validating numerical field simulation (FEM) tools and magnet design techniques. [...]

Beam Loss Monitoring for Demanding Environments / Holzer, Eva Barbara (CERN)
Beam loss monitoring (BLM) is a key protection system for machines using beams with damage potential and is an essential beam diagnostic tool for any machine. All BLM systems are based on the observation of secondary particle showers originating from escaping beam particles. [...]

Development of an Ionization Profile Monitor Based on a Pixel Detector for the CERN Proton Synchrotron / Storey, James (CERN) ; Bodart, Dominique (CERN) ; Dehning, Bernd (CERN) ; Levasseur, Swann (CERN) ; Pacholek, Piotr (CERN) ; Rakai, Aniko (CERN) ; Sapinski, Mariusz (CERN) ; Satou, Kenichirou (JAEA, Ibaraki) ; Schneider, Gerhard (CERN) ; Steyart, Didier (CERN)
The transverse emittance measurement in the CERN Proton Synchrotron is currently performed using fast rotational wire scanners. These scanners cannot provide continuous bunch-by-bunch measurements and the expected future increase of the beam brightness will lead to an accelerated sublimation of the wire. [...]

Design of a Laser-based Profile Monitor for LINAC4 Commissioning at 50 MeV and 100 MeV / Hofmann, Thomas (CERN) ; Boorman, Gary (Royal Holloway, U. of London) ; Bosco, Alessio (Royal Holloway, U. of London) ; Bravin, Enrico (CERN) ; Gibson, Stephen (Royal Holloway, U. of London) ; Griesmayer, Erich (CIVIDEC, Vienna) ; Raich, Uli (CERN) ; Roncarolo, Federico (CERN)
A laser-based profile monitor has been designed for commissioning of CERN's LINAC4 accelerator at 50 MeV and 100 MeV, as part of the development of a non-destructive profile and emittance monitor foreseen for the final 160 MeV beam. The system is based on a low power laser which is scanned through the H⁻ beam. [...]

A High Dynamic Range Diamond Detector Readout System for the CERN Beam Wire Scanners Program / Sirvent Blasco, Jose (CERN) ; Dehning, Bernd (CERN) ; Dieguez, Angel (Barcelona U.) ; Emery, Jonathan (CERN)
A secondary particle shower acquisition system is under design for the upgrade of CERN's beam wire scanners. The system needs to be capable of performing bunch-by-bunch synchronous measurements with an integration time of 25 ns and to cope with signal variations of up to 6 orders of magnitude. [...]
