Les premières données avec ATLAS et le calorimètre à Argon Liquide: des muons cosmiques aux premières collisions à 0.9 et 2.36TeV

par Dr Paolo Iengo, Dr Sandrine Laplace

Auditorium M. Vivargent (LAPP)

The ATLAS Liquid Argon Calorimeter has been commissioned with cosmic muons and "beam splash" events during the years 2008 & 2009. A paper has been submitted to EPJC "Readiness of the ATLAS Liquid Argon Calorimeter for LHC Collisions" and is in the process of being accepted as a publication. The performance obtained will be presented in the first part of the seminar. Since the 23rd of November, ATLAS has collected collisions data at 0.9 and 2.36 TeV. The study of the detector reponse and of the reconstruction algorithms with collision data (very important step to carry on with success the vast LHC physics program) complements nicely the earlier sudies. The second part of the seminar will be devoted to the presentation of the first results.
