Currently, the particle accelerator that produces the highest energy collisions is the Tevatron at the Fermi National Accelerator Laboratory (Fermilab) near Batavia, Illinois. In the Tevatron, protons and antiprotons with kinetic energies of 1 TeV (= 1000 GeV) travel in opposite directions around a ring of radius 1.0 km (6.3 km circumference) before being smashed together, so that the resulting collisions have energies of 2 TeV. The Large Hadron Collider (LHC), currently under construction at the European Center for Nuclear Research (CERN) near Geneva, Switzerland, will achieve collisions between particles with kinetic energies up to 7 TeV so that collisions at an energy of 14 TeV can be examined. What is the goal of studying particle collisions with higher and higher energies?
