In this work, we will study the technical characteristics of two different models of PhotoMultiplier Tubes (Hamamatsu R14755U-100 and Hamamatsu R11187) proposed as light sensors of the calorimeter for Upgrade II at the LHCb. We will also address in detail all methodologies of measurement and data analysis applied during their characterization6 p.application/pdfengcc-by-nc-nd (c) Campos, 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/Tub fotomultiplicadorCalorímetresTreballs de fi de grauPhotomultiplier tubeCalorimetersBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
