Energy deposition and radiation level studies for the FCC-ee experimental insertions / Frasca, Alessandro (CERN ; Liverpool U.) ; Ciarma, Andrea (Frascati) ; Lechner, Anton (CERN) ; Perillo Marcone, Antonio (CERN) ; Humann, Barbara (CERN) ; Järmyr Eriksson, Carl (CERN) ; Welsch, Carsten (Liverpool U.) ; Calzolari, Daniele (CERN) ; Lerner, Giuseppe (CERN) ; Boscolo, Manuela (Frascati) et al.
The Future Circular Collider (FCC) study foresees the construction of a 90.7 km underground ring where, as a first stage, a high-luminosity electron-positron collider (FCC-ee) is envisaged, operating at beam energies from 45.6 GeV (Z pole) to 182.5 GeV (ttbar). In the FCC-ee experimental interaction regions, various physical processes give rise to particle showers that can be detrimental to machine components as well as equipment in the tunnel, such as cables and electronics.

Optimisation of a gas jet-based beam profile monitor for high intensity electron beams / Stringer, Oliver (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Rossi, Adriana (CERN) ; Webber-Date, Alexander (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Churchman, Ashley (CERN) ; Welsch, Carsten (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Castro Sequeiro, C (CERN) ; Schneider, Gerhard (CERN) ; Zhang, Hao (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Sidorowski, Krystian (CERN) ; Ady, Marton (CERN) et al.
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. [...]

Design of a Prototype Gas Jet Profile Monitor for Installation Into the Large Hadron Collider at CERN / Veness, Raymond (CERN) ; Ady, Marton (CERN) ; Castro Sequeiro, Cristina (CERN) ; Forck, Peter (Darmstadt, GSI) ; Kumar, Narender (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Papazoglou, Ioannis (CERN) ; Rossi, Adriana (CERN) ; Salehilashkajani, Amir (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) et al.
The Beam-Gas Curtain or BGC is the baseline instrument for monitoring the concentricity of the LHC proton beam with a hollow electron beam for the hollow e-lens (HEL) beam halo suppression device which is part of the High-Luminosity LHC upgrade. The proof-of-principles experiments of this gas-jet monitor have now been developed into a prototype instrument which has been built for integration into the LHC ring and is now under phased installation for operation in the upcoming LHC run.

Simulations of Space-Charge and Guiding Fields Effects on the Performance of Gas Jet Profile Monitoring / Sedláček, Ondrej (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U. ; CERN) ; Forck, Peter (Darmstadt, GSI) ; Kumar, Narender (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Mazzoni, Stefano (CERN) ; Salehilashkajani, Amir (Cockcroft Inst.

Tech. ; Liverpool U.)
Gas jet based profile monitors inject a usually curtain shaped gas jet across a charged particle beam and exploit the results of the minimally invasive beam-gas interaction to provide information about the beam’s transversal profile. Such monitor will be installed as part of the High Luminosity LHC upgrade at CERN in the Hollow Electron Lens (HEL). [...]

Recent Progress on the Commissioning of a Gas Curtain Beam Profile Monitor Using Beam Induced Fluorescence for High Luminosity LHC / Mazzoni, Stefano (CERN) ; Ady, Marton (CERN) ; Forck, Peter (Darmstadt, GSI) ; Jones, Owain Rhodri (CERN) ; Kumar, Narender (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Papazoglou, Ioannis (CERN) ; Pasquino, Chiara (CERN) ; Rossi, Adriana (CERN) ; Sadovich, Sergey (CERN) ; Salehilashkajani, Amir (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) et al.
For the high-luminosity upgrade of the Large Hadron Collider, active control of proton/ion beam halo will be essential for safe and reliable operation. Hollow Electron Lenses can provide such active control by enhancing the depletion of halo particles, and are now an integral part of the high luminosity LHC collimation system [...]
