Beam gas curtain monitor: Vacuum studies for LHC integration and operation / Castro Sequeiro, C (CERN) ; Ady, M (CERN) ; Bregliozzi, G (CERN) ; Chatzigeorgiou, N (CERN) ; Churchman, A R (CERN) ; Kersevan, R (CERN) ; Lefevre, T (CERN) ; Mazzoni, S (CERN) ; Pigny, G (CERN) ; Rossi, A (CERN) et al.
A beam gas curtain (BGC) monitor has been designed to obtain information about the relative position between the LHC proton beam and the hollow electron lens electron beam through a minimally invasive process. Its working principle relies on intersecting the path of both beams with a supersonic gas curtain, introduced transversely into the LHC beamline, to produce a fluorescence signal. [...]

Optical transition radiation measurements of a high intensity low energy hollow electron beam on electron beam test facility / Sedlacek, Ondrej (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech. ; CERN) ; Rossi, Adriana (CERN) ; Webber-Date, Alexander (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Churchman, Ashley (CERN) ; Welsch, Carsten (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Sequeiro, Cristina (CERN) ; Schneider, Gerhard (CERN) ; Zhang, Hao (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Sidorowski, Krystian (CERN) ; Ady, Marton (CERN) et al.
Optical Transition Radiation (OTR) is commonly used in imaging systems of highly relativistic charged particle beams as the light yield and collection efficiency increase with beam energy. For low beam energies, scintillating screens are typically preferred but they saturate or even get damaged when using a high beam current. [...]

Tech.) ; Sequeiro, C Castro (CERN) ; Wenander, Fredrik (CERN) ; Schneider, Gerhard (CERN) ; Sidorowski, Krystian (CERN) ; Ady, Marton (CERN) et al.
The Hollow Electron Lens (HEL) was proposed to actively remove the beam halo of the proton beam for the HL-LHC upgrade. Currently, the concept of generating such an electron beam is being tested in a dedicated Electron Beam Test Stand (EBTS) at CERN. [...]

A beam profile monitor using gas jet technology is being designed and manufactured at the Cockcroft Institute for high intensity electron beams. It generates a thin, supersonic gas sheet that traverses the beam at a 45-degree orientation and measures the beam-induced fluorescence interactions to produce a 2D beam profile image. [...]

Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary Terrestrial Very-Long-Baseline Atom Interferometry Workshop (TVLBAI 2023)   13 - 14 Mar 2023  - CERN, Geneva, Switzerland  / Abend, Sven (Leibniz U., Hannover); Allard, Baptiste (LCAR, Toulouse); Alonso, Iván (Balearic Islands U.); Antoniadis, John (Crete U.); Araújo, Henrique (Imperial Coll., London); Arduini, Gianluigi (CERN); Arnold, Aidan S. (SUPA, UK ; Strathclyde U.); Aßmann, Tobias (Ulm U.); Augst, Nadja (DLR, Neustrelitz); Badurina, Leonardo (King's Coll. London ; Caltech) et al.
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world to discuss the exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter and gravitational waves.

AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space / AEDGE Collaboration
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range between the most sensitive ranges of LISA and the terrestrial LIGO/Virgo/KAGRA/INDIGO experiments. This interdisciplinary experiment, called Atomic Experiment for Dark Matter and Gravity Exploration (AEDGE), will also complement other planned searches for dark matter, and exploit synergies with other gravitational wave detectors.
