  1. WHAT DO PARTICLE PHYSICISTS DO?Frontiers of Particle Physics 11 Kevin McFarland’s (Univ. of Rochester) presentation” What do you mean you don't work at the LHC?" A report from the other frontiers of particle physics,” 5/31/2008

  2. What is luminosity? L = f n N1 N2/A f is the revolution frequency (c/27 km) N: # of bunches each beam in the storage ring. (2808 bunches) N1,2 is the number of particles in each bunch (billions) A is the cross section of the beam (40 μm)

  3. THE STRUCTURE AND FUNCTION OF THE PARTS OF THE LHC Detectors • 6 areas around circumference that will collect and analyze data • ATLAS • CMS • ALICE • LHCb • TOTEM (minor study) • LHCf (minor study)

  4. Pictorial History of the LHC 19th September 2008 – LHC explosion due to bad soldering joint between two magnets – repairs took 14 months 44
