The Large Hadron Collider at CERN near Geneva, Switzerland recorded its first particle collisions today as proton beams race round the ring in opposite directions. UC Davis physicist John Conway blogs about the startup here.
Conway writes that by the end of the year the collisions should exceed the power of what has up till now been the world’s most powerful particle accelerator, the Tevatron at Fermilab in Illinois, and reach a target of 7 TeV by early 2010.
A slideshow of some of the UC Davis physicists involved with the LHC is here. Just in case anything goes wrong, there’s always this panic button.
