From CERN: “LHC achieves 2011 data milestone”

Geneva, 17 June 2011. Today at around 10:50 CEST, the amount of data accumulated by LHC experiments ATLAS and CMS clicked over from 0.999 to 1 inverse femtobarn, signalling an important milestone in the experiments’ quest for new physics. The number signifies a quantity physicists call integrated luminosity, which is a measure of the total number of collisions produced. One inverse femtobarn equates to around 70 million million1 collisions, and in 2010 it was the target set for the 2011 run. That it has been achieved just three months after the first beams of 2011 is testimony to how well the LHC is running.

‘ It’s great to have delivered this amount of data in time for the main summer conferences,’ said CERN’s Director for Accelerators and Technology, Steve Myers. ‘ When we set ourselves the objective of achieving one inverse femtobarn in 2011, it was for good reason: that amount of data could well give us access to exciting new physics.'”
