Orbit Studies for the 100 MeV Aladdin Racetrack Microtron Injector

This paper describes the computer simulation of electron motion in the 100 MeV racetrack microtron used as an injector on the SRC/Aladdin storage ring. Further details on these machines appear elsewhere in these proceedings. These computations are for a single particle free to move in all three spacial dimensions. Programing utilizes idealized field models to simplify investigation of different machine configurations and to speed computations. First the program is used to assure that a central (having zero phase and transverse oscillation amplitudes) particle is properly accelerated. Then the motion of particles differing in initial phase and transverse coordinates is assured. The survival of particles under these varying conditions provides, then, information about the stability limits of the machine.
