Impedance and thermal studies of the CERN SPS wire scanners and mitigation of wire heating / de la Fuente, Elena (CERN) ; Papazoglou, I (CERN) ; Sito, Leonardo (CERN) ; Andreazza, William (CERN) ; Antuono, Chiara (CERN) ; Bruchon, N (CERN) ; Calaga, Rama (CERN) ; Carra, Federico (CERN) ; Emery, J (CERN) ; Harrison, Anthony (CERN) et al.
All wires of the four CERN SPS rotational wirescanners broke when increasing the beam intensity towards the target for the LHC Injector Upgrade in 2023. Impedance and thermal studies were immediately launched, with simulations and measurements indicating that beam induced heating from resonant modes on the thin wire could be sufficient to cause these breakages.

Commissioning of a Gas Jet Beam Profile Monitor for EBTS and LHC / Zhang, Hao (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Ady, Marton (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.) ; Schneider, Gerhard (CERN) et al.
A gas jet beam profile monitor was designed for measuring the electron beam at the electron beam test stand (EBTS) for the Hollow electron lens (HEL) and the proton beam in the large hadron collider (LHC). It is partially installed in the LHC during the second long shutdown. [...]

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. [...]

A gas curtain beam profile monitor using beam induced fluorescence for high intensity charged particle beams / Salehilashkajani, A (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Zhang, H D (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Ady, M (CERN) ; Chritin, N (CERN) ; Forck, P (Darmstadt, GSI) ; Glutting, J (CERN) ; Jones, O R (CERN) ; Kersevan, R (CERN) ; Kumar, N (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Lefevre, T (CERN) et al.
A minimally invasive transverse beam profile monitor based on supersonic gas curtain technology and beam-induced fluorescence has been developed and demonstrated. The concept presented can be used to measure both the profile of the proton beam in the Large Hadron Collider (LHC) and the concentricity of the electron and the proton beams in the LHC hollow electron lens.

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 [...]
