Fermilab produced 10 fb in the first decade of the 21st century. Fermilab's Tevatron took about 4 years to reach 1 fb in 2005, while two of CERN 's LHC experiments, ATLAS and CMS, reached over 5 fb of proton–proton data in 2011 alone. In April 2012 the LHC achieved the collision energy of 8 TeV with a luminosity peak of 6760 inverse microbarns per second; by May 2012 the LHC delivered 1 inverse femtobarn of data per week to each detector collaboration. A record of over 23 fb was achieved during 2012. As of November 2016, the LHC had achieved 40 fb over that year, significantly exceeding the stated goal of 25 fb. In total, the second run of the LHC has delivered around 150 fb to both ATLAS and CMS in 2015–2018.
