Large Hadron Collider
![Page 2: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/2.jpg)
What is LHC ?
![Page 3: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/3.jpg)
The Large Hadron Collider is the world’s largest and most powerful particle accelerator
![Page 4: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/4.jpg)
It is a 27 km ring of magnets with accelerating structures,

that push the energy of the
particles along the ring
![Page 6: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/6.jpg)
The LHC is located in Geneva, in Switzerland
![Page 7: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/7.jpg)
Currently, there are five experiments at the LHC
![Page 8: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/8.jpg)
CMS
![Page 9: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/9.jpg)
ALICE
![Page 10: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/10.jpg)
LHCb
![Page 11: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/11.jpg)
ATLAS
![Page 12: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/12.jpg)
TOTEM
![Page 13: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/13.jpg)
ALICE, ATLAS, CMS, and LHCb are built in
four huge underground caverns,
![Page 14: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/14.jpg)
that are built around the four
collision points of the LHC beams
![Page 15: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/15.jpg)
LHC Structure…
![Page 16: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/16.jpg)
Two beams Hadrons, will travel in opposite directions inside the
accelerator
![Page 17: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/17.jpg)
Every time the subtomic particles go around the ring, they
gain more energy, hence go faster
![Page 18: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/18.jpg)
Then, physicists will use the LHC to reproduce the conditions just after the Big Bang
![Page 19: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/19.jpg)
![Page 20: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/20.jpg)
They will do this by colliding the two
beams at very high energy
![Page 21: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/21.jpg)
![Page 22: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/22.jpg)
Expert physicists and experts gather from all over
the world to help out with these experiments
![Page 23: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/23.jpg)
No one will know what will happen as a result of these collisions…
![Page 24: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/24.jpg)
…as this experiment is a
never before tried experiment
![Page 25: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/25.jpg)
So kids…
![Page 26: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/26.jpg)
don’t try this at home
![Page 27: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/27.jpg)
Past
![Page 28: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/28.jpg)
In the begining of the 1900s, Europe
dominated in physics
![Page 29: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/29.jpg)
But unfortunatley, the conflicts of the 1930s-1940s held back
european science
![Page 30: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/30.jpg)
By the early 50s, the Americans had understood that further progress needed more sophisticated instruments.
![Page 31: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/31.jpg)
But while Americans were developing new
instruments…
![Page 32: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/32.jpg)
european scientists were still using basic instruments and proceeding slower.
![Page 33: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/33.jpg)
Physicists like Rabi, Amaldi, Auger and Rougemont
![Page 34: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/34.jpg)
realized that there was only one way
to proceed…
![Page 35: CERN presentation....by Stefano Gallizio](https://reader033.vdocuments.site/reader033/viewer/2022052911/559ee5141a28ab310a8b4776/html5/thumbnails/35.jpg)

So in 1953, CERN was born.
