The Large Hadron Collider overcame some early electrical hurdles and operated at its highest energy level yet as it collected data from smashing protons together.
At an event Tuesday, the officials at CERN, the European Organization for Nuclear Research in Geneva kicked off the Large Hadron Collider (LHC) experiments. LHC started at an energy three and a half times higher than previously achieved at a particle accelerator. The successful experiment culminated a 16-year, $10 billion quest to collide subatomic particles.
Gallery: LHC’s biggest collision yet
In September 2008, the proton beams were successfully circulated in the main ring of the LHC for the first time but 9 days later operations were halted due to a fault between two superconducting bending magnets. Repairs and safety features took more than a year to implement. In November 2009, proton beams were circulated again.
The LHC event put those hurdles in the rear view mirror. Beams collided at an energy level of 7 trillion electron volts (7 TeV), with two beams each operating at 3.5 TeV. CERN1 Director General Rolf Heuer said “it’s a great day to be a particle physicist.”
LHC is designed to look for dark matter, new dimensions and the Higgs Boson. The Higgs boson is a hypothetical massive scalar elementary particle predicted to exist by the Standard Model in particle physics. The LHC is a 27km ring deep beneath the French-Swiss border.
CERN’s business is fundamental physics, finding out what the Universe is made of and how it works. The LHC will give CERN more tools for its quest—especially as energy levels rise.
