Abstract

We describe the technique of longitudinal beam transfer function (BTF) for measuring several properties of longitudinal oscillations in a electron storage ring such as the synchrotron frequency, radiation damping time, and bunch length. The technique takes advantage of the Gaussian distribution of longitudinal oscillation amplitudes within the bunch at very low current and the dependence of synchrotron frequency on amplitude. Results of measurements made at the Advanced Light Source (ALS) are presented
