The December announcement of particle beam energies in excess of one trillion electron volts
made the LHC the world's highest-energy particle accelerator.
This will detect gamma-ray photons between 30 million electron volts
(MeV) and 50 billion electron volts
(GeV) and will locate celestial sources to within about 10 arcminutes.
The particle's mass is around 125 billion electron volts
, about 133 times the mass of a proton.
The collision occurred at the lowest energy possible in the LHC - each beam had just 450 billion electron volts
(GeV), creating a 900 GeV collision.
The gamma rays studied have very high energies, about a million million electron volts
(1 TeV) per photon.
So the Large Hadron Collider was designed to collide protons with energies exceeding several trillion electron volts
. A Higgs boson created in such collisions would exist too briefly to detect.
The beams were injected at 450 billion electron volts
, only a fraction of the energy that scientists will aim for when they attempt to collide two particle beams.
The telescope will detect gamma-ray photons with energies ranging from 20 million electron volts
(MeV) to 300 billion electron volts
(GeV), an energy span previously studied only by the European COS-B satellite in the 1970s and the Compton Gamma Ray Observatory's EGRET telescope in the 1990s.
This subatomic detritus--seen by both ATLAS and the Compact Muon Solenoid detector at the LHC--is suggestive of a Higgs boson with a mass of about 125 billion electron volts
(the mass of a proton is about 1 billion electron volts
Myers, all of the magnets for the collider were trained to an energy above seven trillion electron volts
before being installed, but when engineers tried to take one of the rings' eight sectors to a higher energy last year, some magnets unexpectedly failed.
The biggest accelerators on Earth can boost particles to energies of about a trillion electron volts
(1 TeV), but nature somehow accelerates a few particles to energies a hundred million times greater.
