Status of Beam Instrumentation at the Electron Beam Test Stand at CERN
/ Sameed, Muhammed (CERN) ; Ady, Marton (CERN) ; Burger, Stephane (CERN) ; Cenede, Jean (CERN) ; Churchman, Ashley (CERN) ; Coiffet, Thibaut (CERN) ; Devauchelle, Wilfried (CERN) ; Forck, Peter (Darmstadt, GSI) ; Ganesh, Abhishek (CERN) ; Guillot-Vignot, Franck (CERN) et al.
An electron beam test stand has been designed and constructed at CERN as part of the High Luminosity LHC (HL-LHC) project, in collaboration with the ARIES project, to test components related to the Hollow Electron Lens (HL-LHC) and the GSI Space Charge Compensation Electron Lens (ARIES). This comprehensive test facility incorporates normal conducting solenoid magnets, including horizontal and vertical correctors, which generate fields of fractional Tesla magnitude. [...]

Beam studies using a Cherenkov diffraction based beam position monitor for AWAKE
/ Spear, Bethany (JAI, UK) ; Pakuza, Collette (CERN) ; Senes, Eugenio (CERN) ; Wendt, Manfred (CERN) ; Burrows, Philip (JAI, UK) ; Mazzoni, Stefano (CERN) ; Lefevre, Thibaut (CERN)
A beam position monitor based on Cherenkov diffraction radiation (ChDR) is being investigated as a way to disentangle the signals generated by the electromagnetic fields of a short-pulse electron bunch from a long proton bunch co-propagating in the AWAKE plasma acceleration experiment at CERN. These ChDR BPMs have undergone renewed testing under a variety of beam conditions with proton and electron bunches in the AWAKE common beamline, at 3 different frequency ranges between 20-110 GHz to quantify the effectiveness of discriminating the electron beam position with and without proton bunches present. [...]

Selective electron beam sensing through coherent Cherenkov diffraction radiation
/ Senes, E (CERN) ; Krupa, M (CERN) ; Mazzoni, S (CERN) ; Lasocha, K (CERN) ; Lefevre, T (CERN) ; Shloegelhofer, A (CERN) ; Wendt, M (CERN) ; Davut, C (Manchester U.) ; Karataev, P (JAI, UK) ; Pakuza, C (JAI, UK) et al.
We exploit the coherent emission of Cherenkov diffraction radiation (ChDR) by a relativistic electron beam to sense its position even in the presence of other particle beams. ChDR is produced in alumina inserts embedded in the vacuum chamber walls and recorded in a narrow band centered at 30 GHz. [...]

LHC Upgrades in preparation of Run 3
/ Arduini, G (CERN) ; Baglin, V (CERN) ; Bartosik, H (CERN) ; Bottura, L (CERN) ; Bracco, C (CERN) ; Bradu, B (CERN) ; Bregliozzi, G (CERN) ; Brodzinski, K (CERN) ; Bruce, R (CERN) ; Calviani, M (CERN) et al.
The Large Hadron Collider (LHC) Long Shutdown 2(2019–2021), following LHC Run 2, was primarily dedicated to theupgrade of the LHC Injectors but it included also a significantamount of activities aimed at consolidation of the LHC machinecomponents, removal of known limitations and initial upgrades inview of the High-Luminosity LHC (HL-LHC) to favour the intensityramp-up during Run 3 (2022–2025). An overview of the majormodifications to the accelerator and its systems is followed by asummary of the results of the superconducting magnet trainingcampaign to increase the LHC operation energy beyond the maximumvalue of 6.5 TeV reached during Run 2.

Beam Instrumentation Challenges for FCC-ee
/ Wendt, Manfred (CERN) ; Carideo, Emanuela (CERN) ; Härer, Bastian (KIT, Karlsruhe, IPE) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Mitsuhashi, Toshiyuki (Sokendai, Tsukuba) ; Müller, Anke-Susanne (KIT, Karlsruhe, IPE) ; Niehues, Gudrun (KIT, Karlsruhe, IPE) ; Reißig, Micha (KIT, Karlsruhe, IPE) et al.
For the accelerator-based future of high energy physics at the energy frontier, CERN started to investigate a 92 km circumference Future Circular Collider (FCC), as e⁺/e⁻ collider the FCC-ee will operate at beam energies up to 182.5 GeV. Beside the machine operational aspects, beam instrumentation will play a key role in verifying and optimizing the machine to achieve the ambitious beam parameters and quality. [...]
