After yesterday’s great run at the Large Hadron Collider that CERN DG Rolf Heuer described in management speak as “a game-changing fill“, they have done it again today. With 104 bunches and over 10 trillion protons per beam the peak luminosity has been pushed up to 36/μb/s which nearly doubles the record for the second day in a row. This is also 1.13/fb/year which is significant because their target is to collect 1/fb during 2012. Of course they will need to go higher to reach that target because the peak luminosity cannot be maintained continuously, but another factor of 5 or so should suffice and that is now looking quite achievable.
With just a few weeks left of proton physics this year, the recent pace of development has been faster than at any point since they first started to ramp up the luminosity. If this run continues to a healthy completion tomorrow morning they should be able to collect 1/pb in a single run. It is only a few weeks since they celebrated collecting 1/pb in total.
Update: The fill did indeed surpass 1/pb for CMS, LHCb and ATLAS taking the total delivered past 5/pb
Update (30.sep.2010): There was a short run last night with 152 bunches reaching a new record luminosity of about 48/μb/s. This is nearly half way to the target luminosity for 2010 but hopefully the second half will be much quicker than the first.
