Commissioning of the Elettra fast orbit feedback system

A fast orbit feedback system has been installed at Elettra. It globally corrects the closed orbit at 10 kHz rate using all the BPMs and corrector magnets of the storage ring. Libera Electron has been chosen to upgrade the original detectors in order to provide micrometric accuracy and fast data rate of the beam position measurements. The article reports the experience gained during the commissioning of the system and the first operational results.
