Design of a Transport System for High Intensity Beams

A system has been designed which is calculated to be capable of transporting up to 50 mA of 3 MeV protons a distance of seventy-five feet. The beam is contained within a radius of one inch and its phase plot is optimally matched to the acceptance of the synchrotron. This phase matching is accomplished over a wide range of beam currents by varying the excitation of the final quadrupole doublet. A computer program written to calculate the dynamics of the beam is described and some of its characteristics are discussed.
