Impedance Calculation and Verification in Storage Rings [report]

For both the SLC damping rings and the DAΦNE collider a systematic approach to understanding single bunch, longitudinal, current dependent behavior was taken: First, using a bunch significantly shorter than nominal, a careful calculation of the wakefield of the entire vacuum chamber was obtained. This "pseudo-Green" function was then used in bunch lengthening and instability calculations. We review, for both projects, the history of these calculations and comparisons with measurement.
