Ion optics calculations for the University of Manitoba cyclotron

Abstract

A feasibility study was undertaken with the computer code "MANCOL" to insure that satisfactory beam transport would be available after moving the switching magnet into the vault area. Redesign of the 45* left, 45* right, 30* left, and common beamlines was made using the information gained. With the aid of a much more sophisticated beam transport program "TRANSPORT" all beamlines were studied at various energies. The scope of the study was extended to include the problem of beam extraction or stripping. Using recalibrated magnetic field data in the computer code "ORBCAL", the radii and radial momenta of the stable orbits were determined at certain azimuths for a number of energies. From this data one was able to make an energy versus stripping foil radius plot. A computer code "CBEJ" is also presented which calculates trajectories of extracted particles and the five dimensional matrix of the associated transition.
