Computer Studies of Orbits in High Energy Microtrons

This paper reports briefly several types of orbit calculations performed to study the feasibility and design features of a superconducting 600-MeV split microtron being planned for the University of Illinois. Programs have been written for the Illinois IBM7094 computer to study phase stability in the presence of magnetic field inhomogeneities, vertical defocusing produced by the magnet fringing fields, and axial and radial motion of electrons in the accelerating linac. Some of the calculations are described in a report which is available on request.
