CERN's Intersecting Storage Rings have produced collisions between protons several months ahead of schedule, and experiments are scheduled to begin with the rings around the middle of the year. The first successful collisions occurred on 27 January with 15‐GeV protons, and by 17 February the energy had been boosted to 22.5 GeV. When operated at the full energy of 28 GeV, the collisions will correspond to a beam of 1700 GeV hitting a stationary target.
