European Organization for Nuclear Research. Especially in the year 2000 and in the news, CERN, which we heard frequently in the channels, caused many speculations both politically and religiously. Founded in 1954 with the participation of 12 European countries. CERN is not a new study as it seems; is a product of half a century of labor. The name comes from the initials of the French expansion: Conseil European pour la Recherche Nucleaire.

Who founded CERN?
The European countries that contributed to its establishment in 1954 and still maintain their partnership are Belgium, Denmark, Germany, France, Greece, Italy, Norway, Sweden, Switzerland, the Netherlands, the United Kingdom.
Where was CERN Established?
This giant center, under the agricultural lands on the border between Switzerland and France, has hundreds of buildings, 3500 employees and hundreds of staff, employees and researchers. Of these, about 100 are theoretical physicists, while others are experimental physicists or engineers. CERN has more than 10,000 physicists and engineers all over the world.
What are CERN’s Achievements?
The department where CERN is most popular is the part of the particle accelerators called Large Hadron Collider (LHC). Hereby the protons collide with tremendous heights and an artificial environment close to the universe conditions after the Big Bang. The main purpose is to find answers to many questions about the universe, existence, and creation. As predicted, in today’s world, it is impossible for protons to naturally reach that speed (99% of the speed of light). So LHC is a science and engineering monument with everything.
The LHC, which first started working with 28 GeV accelerator in 1956; In 1976, a further 450 GeV accelerator was introduced to increase its quality. As a result of the activities, new forms of matter were discovered. Scientists also made inventions which are extremely important for particle physicists such as W and Z particles.
CERN’s Achievements in Brief;
1973: Scientists found Neutral flow in Gargamelle.
1983: Discovery of W and Z particles in UA1 and UA2 experiments.
1995: Production of the first anti-hydrogen atoms in the PS210 experiment.
1999: Cern scientists found CP symmetry in the NA48 experiment.
2010: 38 anti-hydrogen atoms were clamped for one to sixth of a second.
2011: The retention time of anti-hydrogen atoms increased to 15 minutes.
2012: In Cern, they found A 125 GeV / c2-weighted boson, similar to the Higgs boson.
