CERN - Large Hadron Collider
- 1. CERN’s Large Hadron Collider
- 3. CERN is European Organization for Nuclear Research
- 4. CERN studies FUNDAMENTAL PARTICLES – the basic particles
- 5. What is the Large Hadron Collider?
- 6. The LARGE HADRON COLLIDER , or the LHC , is a machine built by CERN
- 7. Its point is to solve some questions about the universe
- 8. and to re-create the conditions after the BIG BANG
- 9. Then it will also be possible to see what will happen to the universe later
- 10. because it is approximately 27 km in circumference. Large Hadron Collider
- 11. Large Hadron Collider Hadrons are particles made only of QUARKS. *
- 12. because inside the machine, particles collide. Large Hadron Collider
- 13. * QUARKS and LEPTONS are FUNDAMENTAL PARTICLES
- 14. * Protons and neutrons are made up of QUARKS Electrons are types of LEPTONS
- 15. The first time it was lounged September 2008
- 16. During the first run, the magnets of the LHC cooled down, and the experiment couldn’t be carried out
- 17. It took over a year to fix the LHC
- 18. The next time it was lounged 20 Nov 2009
- 19. We do not know how long the experiment will last since no one has ever done it before
- 20. It might last for years
- 21. How does the LHC work?
- 22. STEP 1:
- 23. Electrons are taken away from hydrogen atoms, so that only protons are left
- 24. OR
- 25. By accelerating lead vapor, electrons are taken away from lead atoms, so that only the nucleus is left
- 26. STEP 2:
- 27. Beams of HADRONS in the LHC are shot in different directions
- 28. At certain points, beams collide, gaining more speed
- 29. The maximum speed that the hadrons can reach is 0.999999991 the speed of light
- 30. Nothing can go faster than light. However, there is no limit to energy
- 31. Scientists hope to gain so much energy that it will be enough to create a model of the
- 32. BIG BANG
