2 LHC: the giant microscope and its large «eyes» LHCb CMS ATLAS Exploration of a new energy frontier in p-p and Pb-Pb collisions ALICE Largest magnetic system (15 GJ) The highest energy accelerator At a temperature colder than outer space Four gigantic underground caverns to host huge detectors LHC ring: 27 km circumference Click here to add footer 2

3 Cosa facciamo 1) Si concentra energia in particelle cariche (acceleratori) 2) Le particelle collidono (ricreando condizioni esistenti subito dopo il Big Bang) 3) La radiazione e particelle che fuoriescono vengono riprese dai Rivelatori Tutto cio richiede tecnologia avanzata e sistemi anche convenzionali molto spinti Click here to add footer 3
