Description

The Large Hadron Collider The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the European Organization for Nuclear Research (CERN) over a ten year period from 1998 to 2008, with the aim of allowing physicists to test the predictions of different theories of particle physics and high-energy physics, and particularly for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry. The LHC is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature. It contains six detectors each designed for specific kinds of exploration. The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the Franco-Swiss border near Geneva, Switzerland. Its synchrotron is designed to collide opposing particle beams of either protons at up to 7 teraelectronvolts (7 TeV or 1.12 microjoules) per nucleon, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus (2.76 TeV per nucleon-pair). It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. On 10 September 2008, the proton beams were successfully circulated in the main ring of the LHC for the first time, but 9 days later operations were halted due to a magnet quench incident resulting from an electrical fault. The following helium gas explosion damaged over 50 superconducting magnets and their mountings, and contaminated the vacuum pipe. On 20 November 2009 they were successfully circulated again, with the first recorded proton–proton collisions occurring 3 days later at the injection energy of 450 GeV per beam.[On 30 March 2010, the first collisions took place between two 3.5 TeV beams, setting the current world record for the highest-energy man-made particle collisions, and the LHC began its planned research program. The LHC will operate at 4 TeV per beam until the end of 2012, 0.5 TeV higher than 2010 and 2011. It will then go into shutdown for 20 months for upgrades to allow full energy operation (7 TeV per beam), with reopening planned for late 2014. Thanks Magik _______________________

Le Grand collisionneur de Hadrons Le Grand collisionneur de hadrons est un accélérateur de particules mis en fonctionnement le 10 septembre 20082 et inauguré officiellement le 21 octobre 2008 au CERN. Situé à la frontière franco-suisse, c’est le plus puissant accélérateur de particules au monde construit à ce jour, dépassant en termes d’énergie le Tevatron aux États-Unis. Il est même présenté comme le plus grand dispositif expérimental jamais construit pour valider des théories physiquesNote. Le LHC a été construit dans le tunnel circulaire (26,659 km de circonférence3) de son prédécesseur, le collisionneur LEP (Large Electron Positron). À la différence de ce dernier, ce sont des protons — de la famille des hadrons — qui sont accélérés pour produire des collisions, en lieu et place des électrons ou des positrons pour le LEP. Ces protons seront accélérés jusqu’à une énergie de 7 TeV, soit près de 7 500 fois leur énergie de masse. L’énergie totale de deux protons incidents sera ainsi de 14 TeV. Le LHC sera également utilisé pour accélérer des ions lourds comme le plomb avec une énergie totale de collision de 1 150 TeV pour le noyau dans son ensemble soit un peu plus de 2,75 TeV par nucléon qu’il contient. Construit dans le tunnel de 3 mètres de diamètre et de 27 km de long qui avait abrité le LEP (1989-2000), foré sous la plaine lémanique entre Genève et le Jura, passant sous le pays de Gex, à une profondeur moyenne de 100 mètres (entre 50 et 175 mètres), le LHC est d’abord un accélérateur-collisionneur circulaire de protons (protons contre protons, ou pp). Le dispositif utilise la technologie du synchrotron. Les deux faisceaux de particules sont accélérés en sens inverse par le champ électrique à très haute fréquence des cavités accélératrices et des klystrons. Ils tournent dans deux tubes jumelés où règne un ultravide, insérés dans un même système magnétique supraconducteur refroidi par de l’hélium liquide. Des aimants additionnels sont utilisés pour diriger les faisceaux aux quatre points d’intersection où des collisions permettront des interactions entre les particules. Merci Magik

Very cool work and great information - and of course, the panic mongers were thoroughly convinced that the world would disappear because man was not meant to know this stuff

OBRIGADO PELA INFORMAÇÃO ISTO É IMPRESSIONANTE PENSO QUE ASSUSTADOR,COMO OS CIENTISTAS SABEM COMO CONTROLAR ISTO E QUAL VAI SER O RESULTADO DESTAS PESQUISAS SOBRE O NOSSO PLANETA A OBRA É FANTÁSTICA.+++++++++++5

Excellent image. This info is amazing as well. There are people that honestly think this thing will create a black hole that will end up swallowing not only the earth but our whole galaxy.

Congratulations on the first LHC-inspired image that I`ve seen posted here. In artist after my own heart. Next up, the elusive Higgs-Boson!!! I wonder what that looks like.
