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. [...]

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. [...]

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.

Radiation levels from a beam gas curtain instrument at the LHC at CERN / Prelipcean, Daniel (CERN) ; Sequeiro, Cristina (CERN) ; Schneider, Gerhard (CERN) ; Lerner, Giuseppe (CERN) ; Ady, Marton (CERN) ; Sedlacek, Ondrej (CERN) ; Veness, Raymond (CERN) ; Garcia Alia, Ruben (CERN)
A prototype Beam Gas Curtain (BGC) monitor was installed at the Large Hadron Collider (LHC) at CERN to provide 2D images of the transverse beam profile during the ongoing Run 3 (2022 to date) and in view of the High Luminosity LHC upgrade (HL-LHC). By design, the BGC operation generates collisions between the beam particles and an injected gas jet proportionally to the beam intensity and the gas density, possibly causing radiation-induced issues to the downstream LHC equipment. [...]

A Snapshot of CERN Beam Instrumentation R&D; Activities / Lefèvre, Thibaut (CERN) ; Alves, Diogo (CERN) ; Boccardi, Andrea (CERN) ; Jackson, Stephen (CERN) ; Roncarolo, Federico (CERN) ; Storey, James (CERN) ; Veness, Raymond (CERN) ; Zamantzas, Christos (CERN)
The CERN accelerator complex stands out as an unique scientific tool, distinguished by its scale and remarkable diversity. Its capacity to explore a vast range of beam parameters is truly unparalleled, spanning from the minute energies of around a few keV and microampere antiproton beams, decelerated within the CERN antimatter factory, to the 6.8 TeV high-intensity proton beams that race through the Large Hadron Collider (LHC).

The LHC Injectors Upgrade (LIU) project was put in place between 2010 and 2021 to increase the intensity and brightness in the LHC injectors to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring reliable operation of the injectors complex up to the end of the HL-LHC era (ca. 2040).

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. [...]
