Rotating sensor for new possibilities on Leitz Infinity Coordinate Measuring Machine / Sanz, C (CERN and Cranfield University) ; Cherif, A (CERN) ; Mainaud-Durand, H (CERN) ; Artoos, K (CERN) ; Morel, F (CERN) ; Morantz, P (Cranfield University) ; Shore, P (Cranfield University) ; Schneider, J (Hexagon Metrology) ; Steffens, N (Hexagon Metrology)
A rotatory mount is being designed at CERN to determine the position of the axis of a 0.1 mm in diameter stretched wire with a sub- micron accuracy. As part of its role as world-wide leader in high energy particle physics, CERN is studying how to build a Compact Linear Collider (CLIC). One of the biggest challenges of this electron-positron collider is the alignment required for all the components acting on the beam: thousands of components will have to be assembled and aligned at the micrometre level.

Study of the electrical centre of a resonant cavity Beam Position Monitor (RF-BPM) and its integration with the main quadrupole for alignment purposes / Zorzetti, S (CERN and University of Pisa) ; Wendt, M (CERN) ; Fanucci, L (University of Pisa)
To achieve the luminosity goals in a next generation linear collider, acceleration and preservation of ultra-low emittance particle beams is mission critical and requires a precise align- ment between the main accelerator components. PACMAN is an innovative doctoral training program, hosted by CERN, with the goal of developing high accuracy metrology and alignment methods and tools to integrate those components in a standalone, automatic test bench.

What is the best displacement transducer for a seismic sensor ? / Novotny, P (CERN and Université Savoie Mont-Blanc) ; Aimard, B (LAPP IN2P3 CNRS Université Savoie Mont-Blanc) ; Balik, G (LAPP IN2P3 CNRS Université Savoie Mont-Blanc) ; Brunetti, L (LAPP IN2P3 CNRS Université Savoie Mont-Blanc) ; Caron, B (Université Savoie Mont-Blanc) ; Gaddi, A (CERN)
This paper presents a development of a seismic sensor for the future Compact Linear Collider (CLIC). Sensor in which three different types of sub-nanometre displacement transducers have been integrated: a Fabry-Pérot interferometer, an optical encoder and a capacitive transducer. [...]

Compact Linear Collider component fiducialisation using Frequency Scanning Interferometry / Kamugasa, S (CERN and ETH Zurich) ; Gayde, J-C (CERN) ; Mainaud-Durand, H (CERN)
The Compact Linear Collider (CLIC) is a next generation electron-positron collider under study at CERN. One of the main technological challenges of this project is the tight pre-alignment tolerances of under 17 µm over a 200 m sliding window for its constituent components. [...]

Mechanical Effects of the Non-Uniform Current Distribution on HTS Coils for Accelerators Wound with REBCO Roebel Cable / Murtomaeki, Jaako (CERN, Geneva, CH and TUT, Tampere, FI) ; van Nugteren, Jeroen (CERN, Geneva, CH and Twente University, NL) ; Kirby, Glen (CERN, Geneva, CH) ; Rossi, Lucio (CERN, Geneva, CH) ; Ruuskanen, Janne (Twente University, NL) ; Stenvall, Antti (Twente University, NL) ; Murtomaeki, Jaako (dir.) (TUT, Tampere, Finland and CERN, Geneva, CH)
Future high-energy accelerators will need very high magnetic fields in the range of 20 T. The EuCARD-2 WP10 Future Magnets collaboration is aiming at testing HTS-based Roebel cables in an accelerator magnet. [...]

Simulation of density measurements in plasma wakefields using photo acceleration / Kasim, Muhammad Firmansyah (John Adams Institute, Oxford) ; Ratan, Naren (Clarendon Lab, Oxford University) ; Ceurvorst, Luke (Clarendon Lab, Oxford University) ; Sadler, James (Clarendon Lab, Oxford University) ; Burrows, Philip N (John Adams Institute, Oxford) ; Trines, Raoul (STFC Rutherford Appleton Lab, Didcot) ; Holloway, James (University College London) ; Wing, Matthew (University College London) ; Bingham, Robert (STFC Rutherford Appleton Lab, Didcot) ; Norreys, Peter (Oxford University and STFC Rutherford Appleton Lab, Didcot)
One obstacle in plasma accelerator development is the limitation of techniques to diagnose and measure plasma wakefield parameters. In this paper, we present a novel concept for the density measurement of a plasma wakefield using photon acceleration, supported by extensive particle in cell simulations of a laser pulse that copropagates with a wakefield.
