Next step … world’s best particle collider!

Today ATLAS has recorded the first collision events at 2.36 TeV.
Still far from the design energy of 14 TeV but already 400 GeV more than the previous best collider, the Tevatron. Also a bit later than I suggested in a previous post, due to some problems last week.
In the plot you see one of the first 2-jet events taken. The lower right inset shows the energy distribution in the eta-phi plane (something like a rolled-out detector).
