SPEAR

SPEAR (originally Stanford Positron Electron Accelerating Ring) was a particle physics collider at the SLAC National Accelerator Laboratory. It began running in 1972, colliding electrons and positrons with an energy of , and collecting data about the resulting particles with the Mark I detector. During the 1970s, experiments at the accelerator played a key role in particle physics research, including the discovery of the meson (awarded the 1976 Nobel Prize in Physics), many charmonium states, and the discovery of the lepton (awarded the 1995 Nobel Prize in Physics).

After its use as a particle collider had been superseded, the facility built for SPEAR was converted to a dedicated synchrotron radiation source for the Stanford Synchrotron Radiation Lightsource (SSRL) beamlines, known as SPEAR2. A major upgrade of the ring completed in 2004 gave it the current name SPEAR3. Provided by Wikipedia
