Large hadron collider is back again after two years which was stopped in February 2013. the most powerful and As James Gillies, head of CERN’s Communications Group explains, “we do basic, curiosity-driven research” into the fundamentals of science and the universe. The 27-kilometer Large Hadron Collider — a subterranean circuit of vacuum-sealed steel pipes, surrounded by a network of eight superconducting magnetic arrays, four giant detector stations, and a plethora of cooling and data-collection machinery — is affectionately known as “the fastest racetrack on the planet.”
Cryogenically-cooled magnets can accelerate beams of hydrogen protons to the ludicrous speed of 11,000 laps per second (or 99.999 percent the speed of light). Smashing together two of these beams travelling in opposite directions generates an enormous release of energy, which is in turn measured by CERN’s researchers as they probe the boundaries of our knowledge about the universe. The Higgs boson, as professor Higgs underlines, is just one small part of that quest for insight.
The SPS and LEP/LHC tunnels are almost entirely outside the main site, and are mostly buried under French farmland and invisible from the surface. the CERN main site from switzerland looking towards France.
There remain plenty of unknowns for the researchers to investigate, such as the theorized existence of dark energy and dark matter, so the Collider’s future looks to be at least as busy and productive as its past.
