A Multipurpose Scintillating Fibre Beam Monitor for the Measurement of Secondary Beams at CERN / Ortega Ruiz, Inaki (CERN) ; Fosse, Loic (CERN) ; Franchi, Jonathan (CERN) ; Frassier, Alexandre (CERN) ; Fullerton, John (CERN) ; Kral, Jiri (CERN) ; Lauener, Joel (CERN) ; Schneider, Thomas (CERN) ; Spanggaard, Jens (CERN) ; Tranquille, Gerard (CERN)
A scintillating fibre beam monitor has been developed at CERN for the measurement of low energy and low intensity secondary beams. This monitor can track the passage of individual particles up to intensities of 10⁷ particles per second per mm², over an active area of 20 cm x 20 cm, and with a spatial resolution of 1 mm. [...]

SPS slow extraction losses and activation: update on recent improvements / Fraser, Matthew (CERN) ; Balhan, Bruno (CERN) ; Barna, Daniel (Wigner RCP, Budapest) ; Bartosik, Hannes (CERN) ; Bernhard, Johannes (CERN) ; Bertone, Caterina (CERN) ; Björkman, Daniel (CERN) ; Borburgh, Jan (CERN) ; Brugger, Markus (CERN) ; Brunner, Kristóf (Wigner RCP, Budapest) et al.
Annual high intensity requests of over $1 \times 10^{19}$ protons on target (POT) from the CERN Super Proton Synchrotron (SPS) Fixed Target (FT) physics program continue, with the prospect of requests for even higher, unprecedented levels in the coming decade. A concerted and multifaceted R&D; effort has been launched to understand and reduce the slow extraction induced radioactivation of the SPS and to anticipate future experimental proposals, such as SHiP [1] at the SPS Beam Dump Facility (BDF) [2], which will request an additional $4 \times 10^{19}$ POT per year.

A Scintillating Fibre Beam Profile Monitor for the Experimental Areas of the SPS at CERN / Ortega Ruiz, Inaki (CERN) ; Bay, Aurelio (Ecole Polytechnique, Lausanne) ; Haefeli, Guido (Ecole Polytechnique, Lausanne) ; Spanggaard, Jens (CERN) ; Tranquille, Gerard (CERN)
The CERN Super Proton Synchrotron (SPS) delivers a wide spectrum of particle beams (hadrons, leptons and heavy ions) that can vary greatly in momentum and intensity. The profile and position of these beams are measured using particle detectors. [...]

SPS Slow Extraction Losses and Activation: Challenges and Possibilities for Improvement / Fraser, Matthew (CERN) ; Balhan, Bruno (CERN) ; Bartosik, Hannes (CERN) ; Bertone, Caterina (CERN) ; Björkman, Daniel (CERN) ; Borburgh, Jan (CERN) ; Conan, Nadine (CERN) ; Cornelis, Karel (CERN) ; Garcia Alia, Ruben (CERN) ; Gatignon, Laurent (CERN) et al.
In 2015 the highest integrated number of protons in the history of the North Area was slow extracted from the CERN Super Proton Synchrotron (SPS) for the Fixed Target physics programme. At well over 1.10¹⁹ protons on target (POT), this represented the highest annual figure at SPS for almost two decades, since the West Area Neutrino Facility was operational some 20 years ago. [...]

Gas Electron Multipliers versus Multiwire Proportional Chambers / Duarte Pinto, Serge ; Spanggaard, Jens (CERN)
Gas Electron Multiplication technology is finding more and more applications in beam instrumentation and at CERN these detectors have recently been adapted for use in transverse profile measurements at several of our facilities. In the experimental areas of CERN's Antiproton Decelerator, low energy Gas Electron Multipliers successfully replaced all Multwire Proportional Chambers in 2012 and another detector type has now been developed for high energy applications in the experimental areas of the SPS, totaling a potential of more than a hundred profile detectors to be replaced by GEM detectors of different types. [...]

Antiproton beam profile measurements using Gas Electron Multipliers / Duarte Pinto, Serge (CERN) ; Carriere, Philippe (CERN) ; Spanggaard, Jens (CERN) ; Tranquille, Gerard (CERN)
The new beam profile measurement for the Antiproton Decelerator (AD) at CERN is based on a single Gas Electron Multiplier (GEM) with a 2D readout structure. This detector is very light, ~0.4% X_0, as required by the low energy of the antiprotons, 5.3 MeV. [...]

Gas Electron Multipliers for the Antiproton Decelerator / Duarte Pinto, Serge (CERN) ; Jones, Rhodri (CERN) ; Ropelewski, Leszek (CERN) ; Spanggaard, Jens (CERN) ; Tranquille, Gerard (CERN)
The new beam profile measurement for the Antiproton Decelerator (AD) at CERN is based on a single Gas Electron Multiplier (GEM) with a 2D readout structure. This detector is very light (~0.4% X0), and measures horizontal and vertical profiles directly in one plane. [...]
