LHC Achieves First Particle Collisions
Restarted this past weekend, CERN announced yesterday that physicists used the Large Hadron Collider (LHC) to smash protons together for the first time. The collision occurred at low energy with each proton beam supplying 450 billion electron volts (GeV) creating a total of 900 GeV. The next stage for the LHC will be to accelerate the proton beams to 1.2 teraelectron volts (TeV) each and collide the beam’s protons. If achieved, this would be the highest energy level yet achieved by any particle accelerator. European Organisation for Nuclear Research (CERN) expects this next stage to occur sometime in the next few days before a planned winter break.
