Description

Libera Brilliance+ is the third generation of BPM electronics which have been running in several light sources around the world. It's adaptive signal processing based on either frequency or time domain provided flexibility to measure both turn-by-turn and single bunch beam position. Furthermore, the long-term stabilization concept based on the crossbarswitch enabled it to achieve the stability required for the fast orbit stabilization. Lately, the System-on-Chip technology provided means for simplifying the BPM electronics concept, which can be now optimized for specific locations in the machine without big compromises on the performance. Looking at the future Low-Emittance rings and the status of the available technology, it is possible to anticipate some of the possible future needs: for example the capability of bunch-by-bunch position measurements can be an enabler for the control of the beam properties at the bunch level. Other interesting aspects are the alternative long-term stabilization techniques like the pilot-tone and temperature stabilization.
After an overview of the current BPM electronics use-cases and achievements, this contribution will present the investigations and first steps being done towards a future concept of BPM electronics.
