History of experiments cern
A brief history of cern experiments1954 - founded the CERN-one of the first ventures in Europe, involving 12 countries.
1957 - Manufactured the first synchrotron-accelerator of CERN, who created sets for experimental nuclear and particle physics. Used in nuclear physics, astrophysics and medical physics, and his successor, the Synchrotron Physics, used exclusively in Particle Physics.
1968 - CERN scientist Georges Sarpaki produces a box of gas (multiwire proportional chamber), which counts the particles a thousand times more accurate than previous detectors.
1971 - With the throttle ISR (Intersecting Storage Rings) made the first proton collisions.
1973 - CERN announces an experiment in the bubble chamber Gkargkamel proving the existence of neutral currents, a very important discovery for understanding the particles of matter and how they interact.
1976 - Manufactured in Ypersynchrotro protons, with a perimeter of 7 km), which generates large sets of experimental work at CERN. With the help of those links, the scientists discovered in 1983 two charged particles, W, and the corresponding neutral Z.
1989 - Manufactured the Large Hadron Collider electron positron (LEP)-the largest electron-positron accelerator with a circumference of 27km the tunnel built the largest engineering project for the season. Experiments proved that there are three generations of particles of matter. The year 2000 ended to give way to the Large Hadron Collider.
1990 - A scientist at CERN, Tim Berners-Lee, discovered the Internet as we know it today in an effort to facilitate communication among scientists. It is also the first set concepts such as the URL, the http and html, and discovers the first machine and the first navigation software.
1994 - The Board of CERN approve the construction of the Large Hadron Collider, which cost $ 9 billion. When in full operation, trillions of protons do about 11 245 revolutions per second ring in approximately 99% of the speed of light.
1995 - The team of the Department of Energy Low Antiproton Ring at CERN creates antidroniou people, is the first time that particles of antimatter combine to form people in an effort to understand the asymmetry of the Universe between matter and antimatter.
2002 - After two experiments at CERN, created and trapped thousands antimatter in `cold ', which is" cumbersome "and can be studied easily.
September 2008 - Begin testing the Large Hadron Collider (LHC) in order to answer questions such as how they created the mass of matter, why nature prefers matter to antimatter, how matter evolved from the first moments of creation of the universe.
After nine days of operation, the LHC switched off due to overheating. The repair costs 30 million dollars.
November 2009 - CERN put back into operation the LHC after a year of repairs. Within one day achieve the movement of particles in the tunnel links, in both cases, reaching back to the level at which the experiment before the temporary closure of the throttle.
November 30, 2009 - Note world record in speed links to the highest power level ever achieved in a particle accelerator.
March 1, 2010 - The Large Hadron Collider is back in operation after damage during the Christmas season.
March 8, 2010 - CERN announces that the purpose of the experiment is to detect dark matter which makes up 25% of the universe, whose existence, however, has not been demonstrated so far.
March 30, 2010 - achieved the largest particle collision energy of all time (7 TeV)
