LHC - the accelerator of charged particles colliding beams, designed to accelerate protons to high speeds, and other high-energy particles.
Further, according to the author: As it turned out on the spot at the LHC accelerator is not alone. Not even two. There are dozens of them.
And more in this series is the latest. In it a small particle, which carries the speed of light, just take a break, and other particles. What for? To fun to watch what happens. But the particles have to fly a long and thorny path, yet it will have the honor to be under the scrutiny of one of the detectors more ... And let physics do not take offense at me for this style story about what they spend their lives. It's actually very difficult to understand the common man, and the more ordinary people to tell others. Thus, the control center of the CMS detector Large Hadron Collider (more LHC). On the screen you can see what happens at the end of the flight of the particle. It collides with another and scatters on the weight of all the small pieces. Hadron Collider named because accelerates hadrons - heavy particles composed of quarks. Collider - because the beams of particles are accelerated in different directions, and then their faces in particular, the scientists needed points. It is for these pictures and buried in the ground this huge 27-kilometer pipe valued at more than $ 5 billion.





The picture is generated in this place. Now Collider disconnect and operational magnets are closed and that there is a collision of particles in the care of millions of sensors. But where does this particle here? Who brought it, and where? After all, nothing comes from nowhere.



And now, it turns out that before the particle smash the trash, she flies to the LHC is quite a big way. And this path goes through a chain of other initial accelerators, including linear and three rings (booster, proton synchrotron, super proton synchrotron), crossing the state border of France and Switzerland. Rather, it is passing underneath. Illegally. The fact that he is at CERN in Switzerland, and the bulk of the 27-kilomertvogo accelerator ring - a 100-meter depth in France. Why? Because some clever and wise head of unknown nationality, decided that it would be cheaper to have ground construction. But let us return to the particle. She arrives at the LHC 7-kilometer accelerator SPS, from which virtually all here once it starts. It was built in 1976. By the way, in the SPS particle also face. Since electrons. The collision formed neutrino that scientists sent in transit to the research center, located in Italy. There's the catch neutrinos continue to work with them. When the author asked how they are transported, he said simply - and through the Alps. They fly through the Earth's crust under a mountain in the Italian Alps, Grand Sasso, in which lives a giant neutrino detector. Imagine now, huh? It should be on the other side of the Alps, a physicist and a net or something there still catch neutrinos arriving from France) and puts them into a special bank ... in the SPS particle also arrives from another collider, namely PS. It was on this road it crosses the state border. Illegally underground ...



A schematic arrangement of a territory uskoritiley CERN looks. Big ring - this is the PS. It continued to disperse the protons, which can then go either manufacturing antiprotons in AD (antiprotobn decelerator), and further feeds them into accelerators SPS - & gt; LHC.



Fly on the particle collider here on such a pipe-magnets, which only 1734 pieces. It is more.



Sasha looks into the superconducting uskoryayushuyu of the tank, which varies the electromagnetic field and accelerates their



Collider first tried to launch in 2008. Then the scientists were able to run for some time to support the continuously circulating beam, but the September 19, 2008 there was a big accident, which resulted in a cryogenic cooling system is damaged, liquid helium has resurfaced and there was an explosion damaged part of the structure and conducting magnets. And the reason was the poor quality of the soldering of the elements. He is pictured below.



Conventional soldering ... but ... because of the fact that it was of poor quality, under the influence of a giant electric arc everything started to melt and resulted in an explosion. Recovery and elimination of consequences of the accident then took the rest of 2008 and part of 2009.



Booster accelerator also is under the ground, but in Switzerland, at the CERN



When scientists need to conduct experiments lrugie (not with protons and other ions) in the booster sometimes fly small particle accelerator lead ions LEIR, built in 2005. Here is one of the smallest accelerators - only on the surface of



I must say that in each of the dozen accelerators are carried out in addition to the total of the experiment, and even their own local research



But where the particle was initially taken? And here. It is for this door, which is only required personal access all begins ...



Here it is - the source of most of the particles. Hydrogen balloon. All of this gigantic scientific machine of a hydrogen molecule using a small balloon. This cylinder is not refilled even once. After all, scientists need very little substance of it ... amazing. The huge ring of the 1,700-ton magnets and tiny molecules for them ...



Next to this cherished room we saw the warehouse. Store and warehouse, nothing unusual. In fact, there are stored all sorts of spare parts for colliders



And close ... Another Access, which could not go with her curiosity.



But it turned out that there occurs another installation, the newest linear accelerator - Linac4



Very soon, this tunnel will house the magnets of the accelerator, and while there is an installation of necessary communications



Hands do not touch !!!



Regular kilometers of cable



Geometry Science



At the beginning of the accelerator is mounted some brilliant installation and drawings are carefully ... Let's see what it is



Ooou because it is the source of protons for Linac4 - a powerful microwave, which separates the electrons from the protons in the hydrogen molecule, and gives them the initial push



That's how it looks close.



Incredibly expensive and complex piece of apparatus.



The first thing installed and working - alarm system. Logically



Once again, we struck, we return to the mortal earth, rising out of the dungeon. Here it is one of the magnets ... And there, in 100 meters below it, exactly the same amount to a long, 27-kilometer chain ...
