1970: ISR main control room

#ThrowbackThursday #TBT

This photo shows the Intersecting Storage Rings (ISR) main control room on the night of 20 October 1970 when a beam of protons was first successfully injected into Ring I. Later, on 27 January 1971, two beams of protons collided in the ISR for the first time.

The ISR was the world’s first hadron collider and performed the first-ever proton-proton and proton-antiproton collisions.
