UA1 experiment approved

29 June 1978

CERN physicist Carlo Rubbia pulls together a team to put forward a proposal for an experiment code-named UA1, for "Underground Area 1", since its location on the SPS requires a large cavern to be excavated. The team grows to involve some 130 physicists from 13 research centres – Aachen, Annecy LAPP, Birmingham, CERN, Helsinki, Queen Mary College London, Collège de France Paris, Riverside, Rome, Rutherford, Saclay, Vienna and Wisconsin. On 29 June 1978, the CERN Research Board accepts the proposal for a huge "general purpose" detector to record proton-antiproton collisions at 540 GeV.
