  1. Welcome to CERN João BENTO BE DepartmentPresentation available at http://cern.ch/jbe/CERN/visits “Magic is not happening at CERN, magic is being explained at CERN.”Tom Hanks

  2. Yourvisitat CERN • Agenda • 30 minutes presentation • 10 minutes movie • Visit of 1 or 2 itineraries for 2 hours • Otherpractical informations • Do not hesitate to askquestions • You cantakepictures and shoot filmeverywhere • Microcosmfreely accessible from 9am till 5pm (downstairs) • CERN Shopfrom 11am till 5pm (hall) • Lavatoriesnearby the Microcosm entrance

  3. Let’sstartwith a presentation • What? • Why? • How? • So what?

  4. What?

  5. What means «  »? 1952 1954 CERN C E R N ConseilEuropéen pour laRechercheNucléaire OrganisationEuropéenne pour laRechercheNucléaire European Council for Nuclear Research European Organization for Nuclear Research EuropeanLaboratory for ParticlePhysics

  7. Why?

  8. Dofundamentalresearch By answering questions like the structure of matter… 4th - 5th century BC End of 19th century Beginning of20thcentury 1960s

  10. Answering fundamental questions… HiggsBoson • How explain particules have a mass? Newton could not explain, neithercanwe… • Whatis 96% of the Universe made of ? Wecanonlysee 4%of itsestimated mass! • Whyisn’tthereantimatterin the Universe? Nature shouldbesymetric… • Whatwas the state of matterjustafter the « Big Bang » ? Travelling back to the earliestnstants of the Universewould help…

  11. Bringing nations togetherandeducate • Hundreds of physics institutes • Half of the world’s particle physicists • Biggest international scientific collaboration • Variousstudents programmes • Over 100 countries

  12. How?

  13. By accelerating and collidingobjects…

  14. Atincrediblelevels of energy! • E=mc2

  15. CERN’sacceleratorschain

  16. The largest particle accelerators • 17 miles (27km)long tunnel • Thousands of superconductingmagnets • Ultra vacuum: • 10x emptierthan on the Moon • Coldest placein the Universe: -271° C • In safe conditions!

  17. The biggest and mostsophisticated detectors • Cathedrals of science100m underground • 600 million collisionsper second detected • by hundreds of • million sensors • Thousands of collaborators • for each detector • In safe conditions!

  18. The most extensive scientific computing grid • 15 Petabytes(15 millions of GB)of data everyyear • 100’000 processors • 200 computer centres around the planet

  19. So what?

  20. Practical applications: the World Wide Web • Was developed in the frame of the LHC project in 1989! • Freely given to the World!

  21. Practical applications: cancer treatment • For both detection and cure of cancers • PET Scans • Hadron Therapy

  22. Practical applications: detectors • Scanning trucks in less than one hour without unloading them!

  23. Practicalapplications:using the Grid • Ultra high-speed processing • of satellite imagery in the • case of natural disasters

  24. And of course… some Nobel prizes! George Charpak “for his invention and development of particle detectors, in particular the multiwire proportional chamber” Carlo Rubbia(with Simon van der Meer) “for their decisive contributions to the large project, which led to the discovery of the field particles W and Z, communicators of weak interaction”

  25. What’s new?

  26. LHC isbacksinceNovember 2009! • 18 to 24 monthsat 3.5 TeV as frommid-Feb 2010 • Then long maintenance phase • 7.5 Tev exploitation in 2012?

  27. Conclusion • Fundamentalresearchlaboratory • World’sbiggest international scientificcollaboration • Pushingtechnology to itslimits • Multiple practical applications • Visitourwebsites:Informations: www.cern.ch • CERN TV: www.youtube.com/cernRecruitment: www.cern.ch/jobs • Thankyou!
