Abstract

The Cornell electron-positron storage ring (CESR) luminosity has increased by a factor of >3 over the last 3 years with a peak luminosity of 8.0×10³² cm^-2 sec^-1 and a record integrated luminosity of 750 pb^-1 for one month. This increase in luminosity is in part due to improved alignment of magnetic elements. Operation with a pretzel orbit in multiple bunch mode places particular importance on alignment because of the side effects of magnetic correctors. We report the improvements in alignment and estimate the effects on colliding beam performance
