Abstract

The commissioning of the digital transverse feedback system at ELETTRA provides a valuable tool for the diagnosis and the study of transverse instabilities. The possibility of visualizing and analyzing the details of the time evolution enables the extraction of information regarding unstable and stable modes, such as growth and damping rates and their dependence on the harmonic sextupole. In this paper we present our first experience with the feedback system as a beam diagnostic tool both in multibunch and in single bunch operation modes
