End of 2011 LHC proton-proton run

October 30^th marked the last day of the 2011 proton-proton run, ending a remarkable period from the data-taking point of view, with more than 5 fb^-1 (inverse femtobarn) being delivered to the experiments. This is five times the goal of one fb^-1, set at the beginning of the year  for the whole 2011 data taking period. After that a one-month operation period devoted to heavy-ion data-taking started, to complete the full physics program of the year.
