Geneva. 15 July, 2010
A month ago we decided to focus fully on commissioning the LHC beam with the goal of establishing the conditions for routine collisions between bunches at design intensity at an energy of 3.5 TeV per beam. This involved optimizing not only the LHC but also the injection of protons from the SPS. The teams made very good progress and the machine now runs smoothly for physics with multiple bunches of 1011 protons per bunch.
This is an excellent achievement for a machine that is still in its infancy, having produced its first collisions at 3.5 TeV only three and a half months ago.
While there remain issues to understand – as is hardly surprising with a new machine operating in a new energy region – the effort on beam commissioning has certainly paid off. The peak luminosity, which depends on the number of protons per beam and how tightly they are squeezed together, has risen by more than a factor of 1000 to a value of 1.4 x 1030 cm-2 s-1.
Increased luminosity means more collisions and more data for the experiments. Today we are already above an integrated luminosity of 200 nb-1. This puts the experiments in an excellent position to present important results in a new energy region at the major international conference, ICHEP 2010, which starts later next week.
