LUCID-3 : the upgrade of the ATLAS luminosity detector for High Luminosity LHC
The ATLAS physics program at the High Luminosity LHC (HL-LHC) calls for a precision in the luminosity measurement of ±1%. A larger uncertainty would represent the dominant systematic error in some precision measurements, including the Higgs sector. To fulfil such requirement in an environment characterized by up to 140 simultaneous interactions per bunch crossing (200 in the ultimate scenario), AT
