Accelerators  updated October 3, 2005  D. Carrigan carrigan@fnal.gov (subject line must be sensible)

After World War II a new set of accelerators came on line including the Chicago synchrocyclotron. The control room is shown on the right with Enrico Fermi at the console. In just twenty-five years this family of accelerators had developed into the powerful particle acclerator complex shown below at Fermilab. The Fermilab Tevatron now generates collisions of one TeV protons and antiprotons. In the next several several years CERN's Large Hadron Collider (LHC) spanning the Swiss-French border will come into operation. That machine will be seven times more powerful than Fermilab. The magnet is shown in cross section in the lower right panel. Future accelerators beyond the LHC will be a substantial challenge for the remaining part of our 100 years.
