Prospettive per il Run 2 ad LHC / Ciulli, Vitaliano (INFN, Florence)
With the approach of resumption of the activity of the Large Hadron Collider at the CERN, scheduled for the spring of 2015, the physicists of the ATLAS and CMS experiments are pondering the prospects that will be opened up by the increase of centre-of-mass energy from 8 to 13 TeV, after the discovery of the Higgs boson. However the results from Run 2 go, they will mark an important new chapter in the physics of fundamental interactions, making it possible to explore the region up to around 1 TeV of mass in the search for new particles that can explain dark matter and the other unresolved questions of the Standard Model..

PACMAN STUDY OF FSI AND MICRO-TRIANGULATION FOR THE PRE-ALIGNMENT OF CLIC / Kamugasa, William Solomon (CERN) ; Vlachakis, Vasileios (CERN)
The alignment precision of linear colliders is extremely demanding owing to the very narrow beam size at the interaction point. Unlike circular colliders, particles in linear colliders have only one chance to collide and are hence tightly focused to maximise the number of interactions per collision. [...]

Status of PACMAN Project at CERN / Catalan-Lasheras, Nuria (CERN) ; Mainaud-Durand, Hélène (CERN) ; Modena , Michele (CERN)
Though the Large Hadron Collider (LHC) at CERN is just at the start of a program expected to run for 20 additional years, CERN is studying the next generation of colliders, like the Compact Linear Collider (CLIC). This project proposes an electron-positron collider with a length close to 50 km and with a centre of mass energy of 3 TeV at the collision point. [...]

PERFORMANCE OF THE STRETCHED- AND VIBRATING-WIRE : PERFORMANCE OF THE STRETCHED- AND VIBRATING-WIRE LOCATING QUADRUPOLE MAGNETIC AXES / Arpaia, Pasquale (University of Napoli Federico II, CERN) ; Caiazza, Domenico (CERN , University of Sannio) ; Petrone, Carlo (CERN) ; Russenschuck, Stephan (CERN)
A systematic comparison of performance of stretched-wire and vibrating-wire methods for measuring the magnetic axis of a reference quadrupole magnet is presented. The compatibility of the two measurements is demonstrated and the precision of the two methods is compared as a function of the magnet gradient. [...]

Calibrating the sensing-coil radius by feed-down from a harmonic reference / Arpaia, Pasquale (University of Sannio, CERN) ; Buzio, Marco (CERN) ; Koster, Oliver (CERN) ; Russenschuck, Stephan (CERN) ; Severino, Giordana (University of Sannio, CERN)
A method for calibrating the radius of rotating, harmonic sensing coils is proposed that allows relaxing constraints on alignment and field errors of the reference quadrupole magnet. Radius calibration considering roll angle misalignment between the measurement bench, the magnet, and the motor-drive unit is studied first [...]

Challenges in measuring the longitudinal field Challenges in measuring the longitudinal field / Arpaia , Pasquale (University of Sannio , CERN) ; Caiazza, Domenico (CERN) ; Petone, Carlo (CERN) ; Russenschuck, Stephan (CERN)
A vibrating wire is used to measure the longitudinal profile of the magnetic flux density in the aperture of a non-periodical structure such as a quadrupole accelerator magnet. Limitations in terms of measurement repeatability and uncertainty are observed. The possible causes are investigated by experimental characterization of the measurement system. [...]
