Today we witnessed the first collision events at the Large Hadron Collider at 7 TeV (centre of mass energy). The build-up started at around 6am European Time when they started the first attempt to ramp the energy of the beams up to 3.5 TeV. In fact it was not until the third attempt that they finally got the beams up to the required energy and saw the first events at 1pm.
In case you missed it, here is a recording of the webcast from CERN at the crucial moment.
Here is what a 7TeV event looks like in the LHCb experiment
If you still have not has enough here is another video of the occasion from the ATLAS control room.
If that’s too much, be grateful. I recorded about 30 hours of video stream and these are the exciting parts.
