At R207

At the centre, a barrel shaped hodoscope surrounds the beams' crossing point. It was previously used for experiments R205 and R206 which did run in 1974. After their completion in mid 1975 the equipment of R205 was removed, and that of R206 was modified and rearranged to create two small angle spectrometers, one on each side of the intersection, for experiment R207 (diffraction dissociation and formation at small momentum transfer), by the CERN-Holland-Manchester Collaboration.
