A titan awakes

At approximately 2:40 am Central European Time, ATLAS saw particles from the LHC for the first time in 2010.  As in previous LHC turn-on periods the first thing we see are beam splashes from the LHC beams as they slowly thread the beam through the LHC ring for the first time.

All Bunched Up!

High Energy Physicists have been waiting for many years to see the LHC turn on.  Now that it has been turned on, the network of physicists around the world have quickly been harnessed.  It can be considered a phase transition in particle physics.

First collisions in ATLAS

A few days ago, loud cheers and happy faces filled the ATLAS Control Room while the whole detector lit up: protons are back at the experiment's door, and everybody forgot in a second the long year of waiting for the Large Hadron Collider (LHC) to resume operation.
