Presentation Transcript

  1. The CERN Scientific Program A tour around the accelerator facilities PH Department

  2. The Mission of CERN Push back the frontiers of knowledge e.g. the secrets of the Big Bang …what was the matter like within the first moments of the Universe’s existence? Develop new technologies for accelerators and detectors Information technology - the Web and the GRID Medicine - diagnosis and therapy Train scientists and engineers of tomorrow Unite people from different countries and cultures

  3. The CERN Accelerators

  4. First stop : LHC

  5. 13.7 Billion Years Today 1028 cm LHC : the High Energy Frontier Big Bang Germany and CERN | May 2009

  6. Big Bang Proton Atom Radius of Earth Earth to Sun Radius of Galaxies Universe LHC Super-Microscope cm Hubble ALMA WMAP VLT Study physics laws of first moments after Big Bang increasing symbiosis between Particle Physics, Astrophysics and Cosmology Germany and CERN | May 2009

  7. Enter a New Era in Fundamental Science Start-up of the Large Hadron Collider (LHC), one of the largest and truly global scientific projects ever, is the most exciting turning point in particle physics. CMS LHCb ALICE ATLAS Enter a New Era in Fundamental Science Search for Higgs Boson, Supersymmetry (Dark matter) , new dimensions,… TOTEM Exploration of a new energy frontier in p-p and Pb-Pb collisions LHC ring: 27 km circumference Germany and CERN | May 2009

  8. The experiments at the LHC • Brilliant performance of the LHC, experiments and Grid computing CMS LHCb ALICE: Heavy ions Pb-Pb collisions √s = 2.76TeV/N Dedicated to flavour physics (b and c quarks) 2011-2012 : p-p collisions at √s = 7 & 8 TeV ≥ 2015 : p-p collisions at √s = 13–14 TeV

  9. 4th July 2012: “ATLAS and CMS observe a new particle compatible with the Higgs Boson ”

  10. Next stop : Isolde

  11. Nuclear Physics nTOF & ISOLDE nTOF (neutron time-of-flight) Measures neutron cross-sections Astrophysics Burning of nuclear waste New experimental area EAR-2 in preparation ISOLDE: radioactive ion beams Nuclear physics Astrophysics Solid State Physics Medical applications Upgrade to higher intensity(HIE-ISOLDE) in progress for 2015+

  12. Antiproton Decelerator

  13. Antiproton & Antihydrogen Physics Matter-Antimatter comparison Very fundamental in the current theory of physics: m = m, g = g H H ATRAP, ALPHA Trapping and spectroscopy of Hbar in a "bottle” ASACUSA Spectroscopy of exotic atoms and of in-flight Hbar BASE Magnetic moment of the antiproton AEgIS Hbar free fall, gravity effect on antimatter Galileo’s experiment for antimatter! AEgIS in 2013

  14. Neutrino physics

  15. Neutrino physics Like quarks, neutrinos exist in different flavors nmntne and their flavour oscillates nmntnmne Has been studied with nm beam sent from CERN to Gran Sasso in Italy (CNGS)Data taking now completed, analysis continues Future neutrino programme at CERN under discussion R&D for large liquid argon detectors approved 3 ntcandidates found so far OPERA Gran Sasso nt CERN nm 732 km

  16. SPS North Hall

  17. Fixed Target Physics Lower energy experiments at PS or SPS (in 1-100 GeV) range allow precision measurements and comparison with theoryDeviations can be sign of new physics at higher energies DIRAC: pionic atoms (completed) COMPASS:muon spin physics, spectroscopy NA61: ion physics, quark gluon plasma NA62: rare K decays, physics run starts in 2014 NA63: electromagnetism in extreme conditions Lead ion collision COMPASS in North Hall (60 m long)

  18. PS East Hall

  19. Other experiments • CLOUD - Study effect of cosmic rays on cloud formation • Cosmic rays “simulated” by T11 beam, clouds created in a large climatic chamber • Relevant to climate change CAST - Search for axions from sunUsing a spare LHC dipole, pointing at sun Study for successor (IAXO) underway

  20. Future accelerators J. Wenninger • LHC, and its upgrade to higher luminosity,is central to CERN program for next decade(s)But need to prepare for what will come after,so future accelerators are under study • LCD – Linear Collider DetectorStudying the detector design for possible future e+e- linear colliders (ILC & CLIC) • FCC – Future Circular ColliderStudy 80-100 km circumference machinepp collisions at 100 TeV, as well as ee or ep • Results from the LHC should help decide

  21. Summary The CERN scientific program is: • Rich and diverse • Covers a wide range of energies from atomic physics to the highest energy frontier • Open to transfer of technology, education and societal problems
