No, they've already sent beams round in one direction, today is the day they start colliding, hence all the uproar and fanfair.
Thats not right... Today they are trying to make the beams circulate the thing for the first time.
"**The ****10th September 2008 is ****LHC **start up date. Everything is now ready for the first injection of proton beams into the LHC on the 10th September 2008."
"Proton beams have already been injected into the first metres of the LHC, to test the injection process, but the first attempt to circulate beams all the way around the LHC will be on the official start up day. If everything proceeds according to plan the beam will circulate all the way around the 27 km long LHC. Over the following months the LHC scientists and engineers will commission the LHC, running beams at higher energy with the intention of beginning collisions, using relatively low energy (5TeV) beams, towards the end of 2008."
