Measurement of the emittance of accelerated electron bunches at the AWAKE experiment / AWAKE Collaboration
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. [...]

The status of the FCC-ee optics tuning / van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; Franchi, Andrea (ESRF, Grenoble) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Chance, Antoine (Paris, CEA) ; Dalena, Barbara (Paris, CEA) ; Järmyr Eriksson, Carl (CERN) ; Carli, Christian (CERN) ; Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne) ; Shatilov, Dmitry (CERN) ; Musa, Elaf (DESY) et al.
With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

Gas jet-based beam profile monitor for the electron beam test stand at CERN / Stringer, O (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Zhang, H (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Ady, M (CERN) ; Butti, D (CERN) ; Churchman, A R (CERN) ; Forck, P (Darmstadt, GSI) ; Kumar, N (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Lefevre, T (CERN) ; Mazzoni, S (CERN) ; Sameed, M (CERN) et al.
A non-invasive bidirectional beam profile monitor using beam-induced fluorescence upon a thin sheet of gas has been developed at the Cockcroft Institute in collaboration with CERN and GSI. This device is particularly suited to the Electron Beam Test Stand, and as such, a bespoke gas injection has been optimized for this specific use-case to provide diagnostics unavailable to conventional scintillator screens.

Overview of beam intensity issues and mitigations in the CERN-SPS fast wire scanners / Veness, Raymond (CERN) ; Guerrero, Ana (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Harrison, Anthony (CERN) ; Salvant, Benoit (CERN) ; Zannini, Carlo (CERN) ; Antuono, Chiara (CERN) ; Vollinger, Christine (CERN) ; de la Fuente, Elena (CERN) ; Carra, Federico (CERN) et al.
A new design of fast wire scanner was installed in the CERN injector complex as part of the upgrades linked to the High-Luminosity LHC Project. Initial operations with these beams were good, but during the planned intensity ramp-up one early 2023, all four SPS scanners failed at the same time. [...]

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. [...]

Chapter 18: Beam Instrumentation and Diagnostics / Bravin, E (CERN) ; Jones, R (CERN) ; Lefevre, T (CERN) ; Veness, R (CERN)
The extensive array of beam instrumentation with which the LHC is equippedhas played a major role in its commissioning, rapid intensity ramp-up and safeand reliable operation. Much of this equipment will need consolidation by thetime the LHC enters the High Luminosity (HL) era while the upgrade itselfbrings a number of new challenges that are currently being addressed.Installation of a completely new final focus system in the two high-luminosity LHC insertions implies the development of new beam positionmonitors to equip the upgraded quadrupole magnets. [...]

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. [...]
