Large Hadron Collider's First Operation Answered
The Large Hadron Collider has been tested on 10, September, 2008.
Look here on Wikipedia if you don't know what a Large Hadron Collider is.
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.
