The Large Hadron Collider

The Large Hadron Collider is an accelerator scheduled for completion in the year 2005 at the CERN laboratory near Geneva Switzerland. It will accelerate protons to an energy of 8 TeV. At that energy, the protons will have a speed only about one part in 130 million slower than the speed of light. 

The Large Hadron Collider at CERN studies the properties of subatomic particles and nuclear matter. 

CERN (Conseil Europeen pour la Recherche Nucleaire) The European Laboratory for Particle Physics, formerly known as the European Organization for Nuclear Research, which is situated close to Geneva in Switzerland and is supported by a number of European nations. It runs the Super Proton Synchrotron (SPS), which has a7-kilometre underground tunnel enabling protons to be accelerated to 400 GeV, and the Lai e Electron-Positron Collider (LEP), in which 50 GeV electron and positron beams are collided. The Large Hadron Collider began operation in September 2008.

Engineering also facilitates science in many ways, the largest scale example being the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (CERN). 

The greatest question is of course the Higgs boson whether it exists and its properties agree with the predictions of the Standard Model. It is expected that the Large Hadron Collider...

The inverse efFect-that is, the dependence of temperature on an external electric field (AT = q-E where q is the electrocaloric coefficient)-is used today in devices for electrostatic cooling to achieve temperatures close to the absolute temperature, as required for experiments conducted in the Large Hadron Collider.

The Large Hadron Collider at CERN was designed to prove or disprove the existence of the Higgs boson. A very powerful particle accelerator was needed, because Higgs bosons might not be seen in lower energy experiments, and because huge numbers of collisions would need to be studied. 

The Higgs potential is introduced ad hoc, and its reality cannot be confirmed experimentally directly, but the consequences of its existence were confirmed by observing the Higgs boson in experiments with the Large Hadron Collider at CERN in 2012. This indirectly confirmed also the idea that aU our observations are about one of the degenerate states of the broken symmetry of the Universe. Similar Higgs-field behavior was observed in superconductors [84] (coherent excited states in superconducting condensates with SSB were predicted earlier [85]). 

Write the principal risk as End of Universe , for which F is very tiny according to the Large Hadron Collider website (the end of the universe is one of the risks), but not zero. Since the Consequence is infinite, then the Risk is infinite. 

In 1999 Matey Mateev became a member of the European Center for Nuclear Research (CERN) in Switzerland. Bulgaria s active participation in CERN s experimental and theoretical research was one of his major services to science and to his country. He became a member of the Committee for Bulgaria s Cooperation with CERN and of the Board of CERN, where he represented Bulgaria throughout the period 1999-2000 and was the team leader of Bulgarian scientists invited to work at the Large Hadron Collider on its activation in CERN.
