The International Linear Collider

 
The International Linear Collider will give physicists a new cosmic doorway to explore energy regimes beyond the reach of today's accelerators. A proposed electron-positron collider, the ILC will complement the Large Hadron Collider, a proton-proton collider at the European Center for Nuclear Research (CERN) in Geneva, Switzerland, together unlocking some of the deepest mysteries in the universe. With LHC discoveries pointing the way, the ILC – a true precision machine – will provide the missing pieces of the puzzle.
Consisting of two linear accelerators that face each other, the ILC will hurl some 10 billion electrons and their anti-particles, positrons, toward each other at nearly the speed of light. Superconducting accelerator cavities operating at temperatures near absolute zero give the particles more and more energy until they smash in a blazing crossfire at the centre of the machine. Stretching approximately 31 kilometres in length, the beams collide 14,000 times every second at extremely high energies – 500 billion-electron-volts (GeV). Each spectacular collision creates an array of new particles that could answer some of the most fundamental questions of all time. The current baseline design allows for an upgrade to a 50-kilometres, 1 trillion-electron-volt (TeV) machine during the second stage of the project. There are also plans for a staged approach starting with a 250-GeV Higgs factory to study the properties of the particle discovered at the LHC in 2012 and then upgrading to 500 GeV.
