A novel generation of fast Beam Wire Scanners (BWS), developed in the framework of the LHC Injectors Upgrade (LIU), has been recently deployed in the 3 LHC injector synchrotrons, accelerating protons from 160 MeV to 450 GeV, during the 2019-2020 LHC long shutdown. The monitors feature high precision motor controller, high resolution wire position monitoring and wide dynamic range secondary particles detectors. [...]

The Digital Signal Processing Chain of the CERN LIU BWS
/ Belohrad, David (CERN) ; Emery, Jonathan (CERN) ; Esteban Felipe, Jose (CERN) ; Goldblatt, Aurélie (CERN) ; Guerrero, Ana (CERN) ; Martin Nieto, Miguel (CERN) ; Roncarolo, Federico (CERN)
Between 2019 and 2023, as part of the LHC Injectors Upgrade (LIU), a major renovation of the CERN wire scanners (BWS) was performed. The main driving force was to prepare the wire scanners for the High-Luminosity LHC (HL-LHC), during which the instantaneous luminosity is expected to double, to around 5× 10³⁴cm⁻²s⁻¹. [...]
