The CERN supercollider consists of a nearly 17-mile long ring of superconducting magnets cooled with 60 tons of liquid helium to -456 degrees Fahrenheit underground. Two beams of protons traveling opposite directions will each achieve an energy of 7 trillion electronvolts, resulting to head-to-head collisions of 14 trillion electronvolts--seven times more powerful that the second most powerful particle accelerator at Fermilab in the U.S.
