ATLAS and CMS are now reporting about 4.2/fb recorded while LHCb recently celebrated their first 1/fb. There are 20 days of proton physics left this year, enough time to bring the total to about 5/fb each for the big two. Some time is being reserved for extra machine development studies looking forward to next years runs.
Last week they collided bunches with 25ns spacing for the first time. Next week they will do this again with more bunches and will also run some pile-up tests. I think this means they will collide some high intensity bunches so the experiments can test their algorithms to see how well they can deal with even higher event pile-ups.
Meanwhile the physics runs continue to collect data and today they established a new peak luminosity record of 3.42/nb/s , beating the record of 3.3/nb/s from a few weeks ago. This suggests that they are returning to some adiabatic intensity increases as the end of the run approaches.
If you are following the physics results don’t miss “Heavy flavor physics with the CMS experiment” this Tuesday and “Searches for Exotic Physics with the ATLAS Detector” next Tuesday. Both talks will probably be webcast live from CERN.
Update 14-Oct-2011: The all-time delivered luminosity for the LHC has now passed 5/fb per experiment. The more important figure for recorded luminosity in ATLAS and CMS is over 4.5/fb with two weeks of proton physics remaining for 2011.
