We model the effects of magnet power supply ripple on the long term dynamic aperture of the SSC lattice by modulating the tunes. The lattice is represented by a Taylor map of twelfth order in the phase space coordinates. The transverse tunes parametrizing the rotation matrix (obtained from the linear terms of the map) are sinusoidally modulated at different choices of amplitude and frequency. Particles are tracked through this modulated map for over a million turns. The tune modulation results in a decrease of the dynamic aperture. The extent of this decrease depends largely on the tune of the lattice and to a secondary extent on the amplitude and frequency of the ripple. 3 refs., 4 figs.
