Abstract
At the Cornell Electron/positron Storage Ring CESR, a fast luminosity monitor has been implemented. The monitor works by measuring the amplitude of oscillation of a given bunch while the corresponding opposing bunch is shaken. A disadvantage with the luminosity monitor is that the monitor signal, besides being a measure of the luminosity, is also dependent upon other factors such as the vertical tune and the vertical beta function at the IP. To overcome this deficiency, a software program has been developed to give a normalized signal that only depends upon the specific luminosity. In HEP conditions, this normalized signal is used as input to an optimizer program that automatically varies machine parameters to keep the luminosity at a maximum.
