Civil Engineering Feasibility Study for CERN’s Future Circular Collider / Stanyard, Joanna Louise (CERN) ; Osborne, John Andrew (CERN)
The European Organization for Nuclear Research (CERN) is currently investigating the feasibility of the “Future Circular Collider” (FCC) as a potential successor to the Large Hadron Collider (LHC). The civil engineering team at CERN have employed a bespoke, interactive, geological tool to consider the suitability of multiple layout options for the FCC, situated in the Geneva Basin, in particular quasi-circular options with circumferences in the order of 100 km. [...]

Preparatory Work for a Fluorescence Based Profile Monitor for an Electron Lens / Udrea, Serban (Darmstadt, GSI) ; Barrios Diaz, Elena (CERN) ; Forck, Peter (Darmstadt, GSI) ; Jones, Owain Rhodri (CERN) ; Magagnin, Paolo (CERN) ; Schneider, Gerhard (CERN) ; Tzoganis, Vasilis (Cockcroft Inst. Accel. Sci. Tech.) ; Veness, Raymond (CERN) ; Welsch, Carsten (Cockcroft Inst. Accel. Sci. Tech.) ; Zhang, Hao (Cockcroft Inst. Accel. Sci. Tech.)
A hollow electron lens system is presently under development as part of the collimation upgrade for the high luminosity up-grade of LHC. Moreover, at GSI an electron lens system also is proposed for space charge compensation in the SIS-18 synchrotron to decrease the tune spread and allow for the high intensities at the future FAIR facility.

Improvements to the LHC Schottky Monitors / Wendt, Manfred (CERN) ; Betz, Michael (CERN) ; Jones, Owain Rhodri (CERN) ; Lefèvre, Thibaut (CERN) ; Levens, Thomas (CERN)
The LHC Schottky monitors have the potential to measure and monitor some important beam parameters, e.g. tune, momentum spread, chromaticity and emittance, in a non-invasive way. [...]

The Cherenkov Detector for Proton Flux Measurement (CpFM) in the UA9 Experiment / Montesano, Simone (CERN) ; Addesa, Francesca (INFN, Rome) ; Burmistrov, Leonid (Orsay, LAL) ; Cavoto, Gianluca (INFN, Rome) ; Dubos, Sebastien (Orsay, LAL) ; Iacoangeli, Francesco (INFN, Rome) ; Puill, Véronique (Orsay, LAL) ; Scandale, Walter (CERN ; Orsay, LAL) ; Stocchi, Achille (Orsay, LAL)
The UA9 experiment at the CERN SPS investigates the possibility to use bent crystals to steer particles in high energy accelerators. In this framework the CpFM have been developed to measure the beam particle flux in different experimental situations. [...]

Scintillation and OTR Screen Characterization with a 440 GeV/c Proton Beam in Air at the CERN HiRadMat Facility / Burger, Stephane (CERN) ; Biskup, Bartolomej (Prague, Tech. U. ; CERN) ; Mazzoni, Stefano (CERN) ; Turner, Marlene (CERN ; Graz, Tech. U.)
Beam observation systems, based on charged particles passing through a light emitting screen, are widely used and often crucial for the operation of particle accelerators as well as experimental beamlines. The AWAKE experiment, currently under construction at CERN, requires a detailed understanding of screen sensitivity and the associated accuracy of the beam size measurement. [...]

Design and Performance of Coronagraph for Beam Halo Measurements in the LHC / Goldblatt, Aurelie (CERN) ; Bravin, Enrico (CERN) ; Mitsuhashi, Toshiyuki (KEK, Tsukuba) ; Roncarolo, Federico (CERN) ; Trad, Georges (CERN)
The CERN Large Hadron Collider is equipped with two Beam Synchrotron Radiation systems (BSR), one per beam. These systems are used to monitor the transverse distribution of the beam, its longitudinal distribution and the abort gap population. [...]

Optimized Cryogenic Current Comparator for CERN's Low-Energy Antiproton Facilities / Fernandes, Miguel (CERN ; U. Liverpool (main)) ; Alves, Diogo (CERN) ; Geithner, Rene (U. Jena (main) ; Helmholtz Inst., Jena) ; Koettig, Torsten (CERN) ; Lees, Andrew (CERN) ; Neubert, Ralf (U. Jena (main) ; Helmholtz Inst., Jena) ; Oponowicz, Ewa (CERN) ; Schwickert, Marcus (Darmstadt, GSI) ; Stöhlker, Thomas (U. Jena (main) ; Helmholtz Inst., Jena) ; Tan, Jocelyn (CERN) et al.
Non-perturbative measurement of low-intensity charged particle beams is particularly challenging for beam diagnostics due to the low amplitude of the induced electromagnetic fields. In the low-energy Antiproton Decelerator (AD) and the future Extra Low ENergy Antiproton (ELENA) rings at CERN, an absolute measurement of the beam intensity is essential to monitor operational efficiency and provide important calibration data for all AD experiments.
