CERN: An In-Depth Look

CERN (near Geneva, Switzerland) was founded in 1954 by 12 European countries and now has 22 “member states.” I have been fortunate to have worked on experiments there since 1976, when the new Super Proton Synchrotron was commissioned. Since the late 1990’s, I have been a member of the Compact Muon Solenoid collaboration, one of the big experiments on CERN's Large Hadron Collider. I worked initially on the development, installation and commissioning of the Electromagnetic Calorimeter, a system of over 75,000 crystals of Lead Tungstate (PbWO_4) to measure the energy and direction of high energy gamma rays, electrons and positrons from collisions in the center of the detector.
