CERN: World’s largest particle collider busts record – First images of collisions at 13 TeV (+Video)

The world’s largest particle smasher broke the record for energy levels late Wednesday in a test run after a two-year upgrade, CERN announced Thursday.
“Last night, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV (teraelectronvolts) for the first time,” the European Organisation for Nuclear Research (CERN) said in a statement.
The LHC’s previous highest energy for collisions was eight TeV, reached in 2012.
In April, it started up again after a two-year overhaul designed to pave the way to experiments at 13 TeV. It has the potential to be cranked up to 14 TeV.
Wednesday’s collisions at the giant lab, housed in a 27-kilometre (17-mile) tunnel straddling the French-Swiss border, are part of a recommissioning programme ahead of an even more ambitious roster of experiments, due to start next month.
“These test collisions were to set up systems that protect the machine and detectors from particles that stray from the edges of the beam,” CERN said.
The LHC allows beams containing billions of protons travelling at 99.9 percent the speed of light to shoot through the massive collider in opposite directions.
