Re: Details of large hadron collider (LHC)?
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, intended to collide opposing particle beams of either protons at an energy of 7 TeV per particle, or lead nuclei at an energy of 574 TeV per nucleus. It is expected that it will address the most fundamental questions of physics, hopefully allowing progress in understanding the deepest laws of nature. The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (570 ft) beneath the Franco-Swiss border near Geneva, Switzerland.

The Large Hadron Collider
The LHC (Large Hadron Collider) is an international project, in which the UK has a leading role. This site includes the latest news from the project, accessible explanations of how the LHC works, how it is funded, who works there and what benefits it brings us. You can access a wide range of resources for the public, journalists and teachers and students, there are also many links to other sources of information. |

Re: Details of large hadron collider (LHC)?
The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.
Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC. |

Re: Details of large hadron collider (LHC)?
dear friend,
it is a very interesting project that the scientists are carrying out.here the electrons are acclerated with a speed of nearly the speed of light i.e 3*10^8 m/sec.The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, intended to collide opposing particle beams of either protons at an energy of 7 TeV per particle, or lead nuclei at an energy of 574 TeV per nucleus. it is located at geneva (switzerland). best of luck |

Re: Details of large hadron collider (LHC)?
It has proved that two entangled degenetate Protons annihilate even though they are identical. Annihilation can occur without antimatter if the Nuclear Force can overcome the Weak Force.
This is normally described with moronic blather relatimg to arcane concepts such as Pauli Exclusion and Fermi Gas which are completely mythical. The Weak Force is induced inverse squared and also acts inversed squared between particles and as such is very hard to overcome. But it is limited to a single Energy Quantum. The attraction produced by degenerate matter quickly overcomes it. The matter antimatter requirement only applies to less energetic non-degenerate particles where there is no means of ovecoming the Weak Force. Another impediment in light speed. Light Speed entanglements never close. Think about cool those magnets. Think about make a perfect vacuum on a 27 Km tube. Those are engineering problems and LHC isn't perfect (http://en.wikipedia.org/wiki/Large_Hadron_Collider#Construction_accidents_and_d elays). Now those problems has been solved, but safety is important. LHC is designed to operate at 14 TeV energy. But now is only operate to 7 TeV. It's half-throttled. Why? Nobody knows if an overheat on a magnet will happen again. On 2012 will operate at 8 TeV and on 2013 will have a technical stop during that year. Only on 2014 will operate above 8 TeV energy, but isn't sure. Only during technical stop on 2013 scientist and engineers decides if it's save operate above 8 TeV. The main purpose of LCH is find any evidence about Higgs particle. But LHC is not alone. There another particle accelerator trying to find it. It's called Tevatron and it's located on Chicago (http://es.wikipedia.org/wiki/Fermilab). Since 2002, the Tevatron is operating with a energy lower than LHC (1.8 TeV), but on that energy 32.000 Higgs particles has been produced but no one has been detected. Why? Well, it's impossible detect the Higgs particle on a direct observation because the particle will disintegrate before reach detector. Those detector only detect the particles in witch Higgs disintegrate. Think about this: Imagine a bean of protons colliding with another bean of protons. Lot of particles will be created and only on a few exceptional cases a Higgs particle will be created but it disintegrate on another particles. To the detector reach the particles created by the crash of lot of protons and 3-4 particle created by the disintegration of the Higgs. There's lot of noise on the detectors and the raw data must have processed by computers trying to reduce the noise (called statistical background). It's necessary Higgs disintegrates on a very rare way to produce a event very different to the background. Of those 32.000 Higgs particles produced since 2002, only 0.2 events will be detected. I mean, since 2002 isn't sure that only 1 event has been produced. But that even has been detected on Fermilab. Data will show us that if that even has been produced by a Higg particle, that particle will have a mass of 201 GeV/c^2. But is a Higg particle or is a fault on the sensors?... There's no evidence about that. But the 32.000 Higgs particles are here: on the data of the sensors, but hide in a lot of statistical background. LHC will change the situation. With more energy, those very rare events will have more probable. But it take month to detect an significant event. Think about this. Billions and billions of collisions is producing day after day. Detectors detect the collisions and transmit the raw data to supercomputers that analyze those data. And on those billions of collisions day after day, only after few months a significant event has been detected. |
