(Liverpool U.) ; Cavoto, G. (INFN, Rome) ; Ceccucci, A. (CERN) ; Chrzaszcz, M. (U. Zurich (main) ; Cracow, INP) et al.
In this chapter we explore a few examples of physics opportunities using the existing chain of accelerators at CERN, including potential upgrades. In this context the LHC ring is also considered as a part of the injector system. [...]

Relative Calibration of the Time Transfer Link between CERN and LNGS for Precise Neutrino Time of Flight Measurements
/ Feldmann, Thorsten (Braunschweig, Phys. Tech. Bund.) ; Bauch, A (Braunschweig, Phys. Tech. Bund.) ; Piester, D (Braunschweig, Phys. Tech. Bund.) ; Alvarez, P (CERN) ; Autiero, D (CERN) ; Serrano, J (CERN) ; Brunetti, G (Lyon, IPN)
—The relative calibration of the GPS time link between European Organization for Nuclear
Research (CERN) and Gran Sasso National Laboratory (LNGS), performed in 2011, is reviewed. “Relative”
means that traveling equipment was used to calibrate the delay of the link as a whole, but no information on
absolute delays of individual components was gained. [...]

This report describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield acceleration and the motivation for using proton drivers. [...]

Measurements of 55Fe activity in activated steel samples with GEMPix
/ Curioni, A (CERN ; Milan Polytechnic) ; Dinar, N (CERN ; Paris U., VI-VII) ; La Torre, F P (CERN) ; Leidner, J (CERN ; RWTH Aachen U.) ; Murtas, F (CERN ; Frascati) ; Puddu, S (CERN) ; Silari, M (CERN)
In this paper we present a novel method, based on the recently developed GEMPix detector, to measure the 55Fe content in samples of metallic material activated during operation of CERN accelerators and experimental facilities. The GEMPix, a gas detector with highly pixelated read-out, has been obtained by coupling a triple Gas Electron Multiplier (GEM) to a quad Timepix ASIC. [...]

Statistics of vacuum breakdown in the high-gradient and low-rate regime
/ Wuensch, Walter (CERN) ; Degiovanni, Alberto (CERN) ; Calatroni, Sergio (CERN) ; Korsbäck, Anders (Helsinki Inst. of Phys.) ; Djurabekova, Flyura (Helsinki Inst. of Phys.) ; Rajamäki, Robin (Aalto U.) ; Giner-Navarro, Jorge (Valencia U., IFIC)
In an increasing number of high-gradient linear accelerator applications, accelerating structures must operate with both high surface electric fields and low breakdown rates. Understanding the statistical properties of breakdown occurrence in such a regime is of practical importance for optimizing accelerator conditioning and operation algorithms, as well as of interest for efforts to understand the physical processes which underlie the breakdown phenomenon.
