After the successful accelerator commissioning and with the facility already in operation one of the top short term objectives pointed out by accelerator division was the Fast Orbit Feedback implementation (FOFB). The target of the FOFB system is to hold the electron beam position at submicron range both in vertical and horizontal planes correcting the inestabilities up to 120Hz. This increased beam stability performance is considered a major asset for the beamlines user operation. To achieve this target, the orbit position is acquired from the 88 Libera BPMs at a 10KHz sampling rate, distributed through an independent network and the corrections are calculated and sent to the 176 power supplies that drive the corrector coils. All this correction loop is executed at 10 KHz and the total latency of the system is characterized and minimized optimizing the bandwidth response.
