LHC Back On

Earlier today, the beam people at CERN were able to successfully inject protons beams going both directions in the LHC at 450 GeV. This is the first time the beam has been circulated in the accelerator since the long shutdown started in 2013. Their job over the next couple months will be to increase the energy and to increase the number of bunches until everything is ready for physics running at the detectors (collisions at 6.5 TeV per beam).
