The last couple of weeks have seen a mixed bag of special runs, luminosity production, machine development and down-time

The number of the events the detector can handle per bunch crossing is limited. Even so, LHCb wants to integrate as much luminosity as possible

The past two weeks have seen luminosity production rates vary somewhat but the overall upwards slope has remained steady

The LHC has been in luminosity production mode for a couple of weeks - the total integrated luminosity for the year has passed 14 inverse femtobarns

A 10% decrease in the LHC's peak luminosity can be explained by changing bunch intensities. Jan Uythoven reports

Good performance followed recovery from extended luminosity calibration runs

A mixed bag of operations and the development of special optics mean the LHC is on track for as much luminosity as possible before the long shutdown

The LHC has delivered more collisions so far this year than in the whole of 2011 - so many it's overheating the magnets

On 16 March beams in the LHC reached the world-record energy of 4 TeV. Stable-beams mode is planned for 3 weeks from now

With powering tests finished, the LHC is being recommisioned to take beams in the first week of April

The cool-down and circuit testing in all LHC sectors restarted 3 weeks ago, and is going well
