R108 set-up at intersection I1, ISR

The experiment aimed to investigate the dilepton spectrum at high mass, and the particles produced in association, and also to the measurement of the particles produced in events containing a neutral pion with large transverse momentum. The detector designed by the CERN-Columbia-Oxford-Rockfeller Collaboration consisted of a superconducting solenoidal magnet, planes of cylindrical drift chambers, scintillation counters, and two arrays each composed of 168 lead-glass Cerenkov counters
