Abstract: We present our experience with the Libera Electron Beam Position Monitor (EBPM) during the first months of operation at Diamond. Measurement noise and beam current dependence with beam are compared to earlier lab measurements. Where discrepancies between the performance in the lab and in the application are observed, the causes have been investigated. Furthermore, results of the integration of the EBPMs into a Fast Orbit Feedback (FOFB) system are presented, uncluding measurements, of orbit motion spectra with and without FOFB.
