Last night at midnight central European time the Large Hard^H^Hdron Collider collided protons for the first time in 2011. They used two bunches per beam and a squeeze beta* of 1.5m at 3.5TeV per beam. Various setting up tasks are still ongoing before the number of bunches can be increased and serious physics can begin, but to have reached this position after just two weeks of running with beams is a very good sign.
Update: Here is a preliminary schedule plan for the first half of 2011 from the Chamonix summary meeting with some extra annotations. Click on it for full size.
