  A common Fast Orbit Feedback (FOFB) application is planned for the new storage rings at MAX IV laboratory and SOLARIS. The application will run in the Beam Position Monitor (BPM) electronics (Libera Brilliance+). Global orbit data concentration will be conducted inside the gigabit data exchange (GDX) modules with a Virtex6 field programmable gate array, which will be daisy-chained around the storage ring. The feedback calculation algorithm is based on the Singular Value Decomposition (SVD) – the PI controller will be applied in the modal space for individual eigenmodes. The calculations will be distributed over all GDX modules to reduce overall latency. Each GDX module will calculate setpoints for four correctors, horizontal or vertical. The new setpoints will be sent directly to the magnet power supply controllers over a serial point-to-point link. This article presents details on FOFB implementation and control topology.

  The new Libera Sync 3 CW reference clock transfer system has been specifically designed to meet the strict requirements of the latest fourth generation light sources, such as the Swiss FEL. The system has been co-developed with the Paul Scherrer Institute (PSI). It has been produced and tested at Instrumentation Technologies (I-Tech) and later installed at PSI. In this article we give a general overview of the system and its functionalities. We also present a brief overview of the supporting products that have been developed in order to enable testing at the level of performance discussed. Finally, we focus on presenting some of the test results obtained at I-Tech and PSI showing the performance capabilities and limitations of the system.
