One of the intersection regions at the CERN ISR, I-8

One of the intersection regions at the CERN ISR, 1-8, where data on proton-proton interactions in the highest range of energies available (as high as an equivalent conventional accelerator energy of 2000 GeV) were being collected. At this intersection region Pisa-Stony Brook and CERN-Rome teams had surrounded the position where the beams cross with detectors. Results from the ISR were among the most important reported at Aix.
