First 7 TeV Proton-Proton Collision Events

On Tuesday afternoon, March 30th, 2010, for the first time the LHC achieved 7 TeV collisions and ATLAS recorded their first proton-proton collision events at this record energy.

Event Displays

   
Event display of a 7 TeV proton collision recorded by ATLAS.   Another display of the same 7 TeV proton collision event.   Display of a jet event at 7 TeV recorded by ATLAS.
   
Display of an event at 7 TeV with a muon candidate.   Display of an event at 7 TeV with Pixel detector fully on.   Another display of an event at 7 TeV with a muon candidate.
 
Display of a 2 jet event at 7 TeV.   Display of on event at 7 TeV with to two inelastic proton-proton collisions (pile up).
