SPEAR (originally Stanford Positron Electron Accelerating Ring, now simply a name)[1]<templatestyles src="Citation/styles.css"/>[a] was a collider at the SLAC National Accelerator Laboratory.[2] It began running in 1972, colliding electrons and positrons with an energy of Script error: No such module "val".. During the 1970s, experiments at the accelerator played a key role in particle physics research, including the discovery of the

Today, SPEAR is used as a synchrotron radiation source for the Stanford Synchrotron Radiation Lightsource (SSRL). The latest major upgrade of the ring in that finished in 2004 rendered it the current name SPEAR3.
Notes
a:<templatestyles src="Citation/styles.css"/>^ The original design consists of a single ring, an upgraded proposal for a pair of asymmetric rings did not receive enough funding and finally the acronym was kept as a simple name.[1] Though the name Stanford Positron Electron Asymmetric Ring is also used in official sources.
