Beam makes it halfway round LHC

Splashing out at the LHC

By Hamish Johnston

Slowly but surely the Large Hadron Collider is coming back to life at CERN in Geneva. Over the weekend the beam was sent halfway round the 27 km ring for the first time since the collider failed last year.

The low-energy beam was then dumped in a collimator just upstream of the CMS cavern and the experiment’s calorimeters and the muon chambers saw the above “splash event”.

Just another 13.5 km (and a few TeV) to go!
