Aerial photograph of the site of CERN,the European Centre for Nuclear Research,showing the outline of the underground Super-Proton- Synchrotron (SPS) accelerator (white dotted line). Geneva & the French Alps are beyond. As well as being employed as an ordinary accelerator,the SPS has also been used since 1983 as a collider,accelerating protons in one direction & antiprotons in the opposite direction within the same circular beam pipe. The resulting proton/antiproton collisions led to the discovery in 1983 & 1984 of the W & Z particles,mediators of the weak nuclear force | |
