SPS reaches its design energy of 400 GeV

17 June 1976

At 2.2 kilometres in diameter the Super Proton Synchrotron is Europe's largest particle accelerator. Commissioning of the accelerator begins in mid-March 1976 using beams of protons. Then on 17 June 1976 the SPS accelerates a beam of protons at its design energy of 400 GeV for the first time. The machine is ready to supply beams to experiments.
