The Atlas Experiment at CERNís LHC  

The Atlas experiment runs at CERNís Large Hadron Collider (LHC) located near Geneva, Switzerland. The LHC provides proton, proton collisions at an energy of 7-14 TeV. The data taking is just beginning (Mar. 2010), but the LHC is already the highest energy accelerator ever.
The SBU group built high voltage feedthroughs and operates electronics for the calorimeter, is providing calorimeter calibration using J/Y mesons, Z and W bosons and converted photons. We also are experts for the pixel detector and are building upgrades to the tracking system...
... and the calorimeter has been tested for two years using ever present cosmic rays...
proton-proton collisions have already occurred and an example is shown below
After years spent building the experiment and the LHC, collisions at 900 GeV, 2.36 TeV and 7 TeV...
Data and simulated event comparison of energy deposited in the Atlas calorimeter by cosmic rays
The first Atlas physics publication "Charged particle multiplicities in pp interaction at sqrt(s) = 900 GeV measured with the Atlas detector at the LHC" has been published in Phys. Lett. B

We're expecting to see something new at the LHC, but what will it be?
  Maybe the Higgs boson
 
    or Supersymmetry
   or maybe even mini black holes...
