Latest developments of Libera BPMs and low-jitter clock distribution system

Abstract: An overview of latest upgrades to storage ring and single-pass BPM instrumentation that was adopted by new machines such as Taiwan Photon Source and MAX-IV. Built-in FOFB application calculates the fresh magnets' values in less than 2 μs. The talk will discuss a solution for real-time two beam flavor measurement.

Xilinx Zynq SoC and Power-over-Ethernet are two highlights of the new instrument platform that can accommodate the booster & storage ring as well as other LINAC and beamline applications. First representative is Libera Spark that will populate a big booster ring at ESRF. Instruments built on this platform have greatly balanced performance/price ratio and are affordable also to facilities with less stringent performance requirements.

Libera Sync 3 is the clock distribution system designed to meet the most strict requirements of 4th generation light sources. It has been co-developed with PSI and tested at Swiss-FEL facility. The system fulfills the requirements of less than 10 fs of jitter and less that 40 fs for phase stability per day.
