| Abstract |
Recent measurements showed that the ALBA transverse impedance model was able to explain 65% of the measured single bunch vertical detuning. * This report shows the revision of the impedance model developed to match latest single bunch measurements performed to evaluate the total effective machine impedance and impedance of specific elements, like in-vacuum undulators or a recently installed pinger magnet. The model improvement includes a better bunch length parameterisation, re-calculation of several vacuum chamber elements with Gdfidl, and inclusion of elements neglected so far in the impedance budget. We also show and discuss the computation of the resistive wall impedance using ImpedanceWake2D.
