Abstract

Within the last year CESR (Cornell Electron Storage Ring) has changed its mode of operation from 7 nearly equally spaced bunches in the two counter-rotating beams to 9 trains of 2 bunches in each of the beams as the next step in the upgrade of the facility toward higher beam currents and increased luminosity. The upgrade program has included work to understand and document the transverse stability of a single beam composed of trains of bunches. Initial results from this work will be reported here
