Abstract

The LHC Injectors Upgrade (LIU) program included new fast beam wire scanners (BWS) to meet the requirements of the higher brightness and intensity High Luminosity LHC (HL-LHC) beams. Seventeen LIU BWS have been installed during the LHC second long shutdown (LS2) and they are currently used in the daily operations of the LHC injectors. After giving an overview of the LIU project and the general beam instrumentation upgrades associated with it, this paper presents a short review of the mechanical design and layout of the LIU BWS, the electronics involved, and then focuses on the first results obtained during their commissioning.
