Abstract :
We report the results of a computer simulation of the PEP-II transverse feedback (TFB) system including single particle transverse beam dynamics and measured RF cavity higher order modes. The simulation addresses issues such as required FB power and gain, noise, bunch offsets, and varying initial bunch conditions. We also summarize a simulation of a proposed mode of operation of the feedback system where selected individual bunches are driven to large amplitudes in order to trim their current
