Abstract Trajectories of the exteral beam of the CERN proton synchrotron in the horizontal plane were calculated and show a moderate defocusing. The vertical motion, obtained for three trajectories by graphical piece-wise integration, show positive focusing. These predictions on particle directions were checked on nuclear emulsions placed in arrays at several distances from the target. At 19 m from the target, the observed focal point for the horizontal flux distribution is precisely the calculated value. Vertical profiles of the scattered proton flux at 37 m distance shows the most nearly parallel beam corresponds to a scattering angle of 28 mradians. A target diagram giving the angular distribution in space of scattered 24-Bev protons indicates that half the tracks lie within a space angle of 1 mradian from the average direction. The beam intensity at 90 m from the target is as high as 4000 protons/cm/sup 2/ per pulse. (J.S.R.)
