Description
The ATLAS experiment was designed to explore a broad variety of phenomena
that may arise in the high energies proton-proton collisions at the Large
Hadron Collider (LHC). It was optimized for the search for the Higgs Boson
in the largest possible mass range as well as for the search for heavy new
particles such as those expected in supersymmetric models. The detector has
been successfully taking data since first LHC collisions in Nov 2009.
Over the last year the experiment collected data with an efficiency of close
to 95% accumulating more than 5/fb of proton-proton data. In this period the
luminosity dramatically increased, leading to a maximum of ~15 interactions
per bunch crossing at the end of the 2011. During 2011 ATLAS also collected
~150/ub of data during the LHC lead-lead collision run.
We present the status of the detector as well as the key aspects of the
detector performance from the 2011 run. In addition we present prospects for
the detector running in 2012 when the LHC will run with higher energy
collisions and at higher luminosities.
