Un des principaux objectifs de l'expérience ATLAS auprès du LHC est l'observations ou l'exclusion de nouvelle physique au-delà du Modèle Standard, en passant par les mesures de sections efficaces de production de processus du Modèle Standard. Sachant que le taux de production d'une particule dépends de sa section efficace de production ainsi que de la luminosité, il est necessaire de mesurer cette luminosité avec une grande précision. L'expérience ATLAS possède plusieurs détecteurs capable de mesurer la luminosité, dont les deux principaux: LUCID (Luminosity measurement Using Cerenkov Integrating Detector), et BCM (Beam Condition Monitor). Ces détecteurs sont calibrés absolument pendant des prises de données dédiées appelés van der Meer sca...
