Particle Beam Collider Work at SLAC

History: SLAC and Stanford have had a very long history of designing, building, and operating electron-positron colliders leading to several Nobel Prizes:

  • CBX [0.13 GeV x 0.13 GeV two ring collider at Stanford 1963-1967]
  • SPEAR [2.5 GeV x 2.5 GeV one ring collider at SLAC 1972-1988]
  • PEP [15 GeV x 15 GeV one ring collider at SLAC 1980-1988]
  • SLC [49 GeV x 49 GeV linear collider at SLAC 1989-1998]
  • PEP-II [3.1 GeV x 9.0 GeV two ring collider at SLAC 1998-2008]


Present research into particle beam colliders includes the following active topics:

  • e+e-, e-p, pp, hh collider designs
  • Interaction region design
  • Accelerator-detector backgrounds
  • High Order Mode (HOM) generation, mitigation, and heat removal
  • Ampere level beam generation and RF power
  • Single beam instabilities
  • Multi-bunch beam instabilities
  • High power collimators
  • Bunch-by-bunch feedback
  • High power fast bunch feedback kickers
  • Injection systems
  • Beam-beam effect
