Experiments around intersection I8, ISR

The lithium transition-radiation detectors and the large liquid argon calorimeters of experiment R806T are shown above and below the intersection at I-8 (Brookhaven-CERN-Saclay-Syracuse-Yale Collaboration, Study of large transverse momentum phenomena by electron and photon detection). At 90 deg to the intersecting beams are the monitoring proporional chambers of experiment R805 (Measurement of real to imaginary ratio of forward scattering amplitude - Coulomb interference - by the CERN-Rome Collaboration). Left and right of the intersection one sees, symmetrically placed around the interaction region, the large scintillation counters hodoscopes used by R801 (Pisa-Stony Brook Collaboration) to measure the pp total cross section and the features of inelastic collisions.
