More bunches in PEP: Single particle dynamics

A luminosity improvement in PEP may be possible by colliding up to 9 bunches in each beam. The beams would be separated using the existing separator plates with a trivial change in the bias polarities and a modification of the betatron functions. In this note, the bunch separation scheme and associated optics are reviewed. The beam separation distance, beam size and long-range beam-beam tune shift are then found as a function of separator plate voltage. 17 refs., 13 figs
