Measurements of Beam Behavior in the Karlsruhe Cyclotron

From the measurements made during the first operation period of the Karlsruhe cyclotron those of radial beam density, phase width and axial beam distribution are mentioned. Because of the satisfactory separation of the single orbits in a large radial range it has been easy to obtain information on the energy gain per turn, the amplitudes of the coherent radial oscillation and the radial dependence of the radial and axial betatron frequencies.
