There’s been great progress made recently at the LHC, with successful commissioning of “trains” of bunches, allowing significantly higher collision rates. Last night’s fill produced an integrated luminosity of .684 inverse picobarns (or 684 inverse nanobarns), which can be compared to the total integrated luminosity up until this week of about 3.5 inverse picobarn. The highest instantaneous luminosity reached is now at about 1/5 the goal set for this year, with a further increase in number of bunches planned for this weekend. For more details, there’s a message from the CERN DG here.
Update: The latest fill, with 104 bunches, recently started, with an initial luminosity now at 1/3 of the goal for this year.
