Isolating the light of a single bunch: determining the viability of operating vertical-plane Pulse Picking by Resonant Excitation at Diamond-II to serve timing mode users
Year: 2026
Type: conference-paper
Abstract: Pulse Picking by Resonant Excitation (PPRE) enables synchrotron facilities to provide single-bunch light for timing users without interrupting multi-bunch operation*. We report the first vertical-plane PPRE tests at Diamond using the Multi-Bunch Feedback system, achieving vertical bunch-size growth and measurable X-ray enlargement. A simple novel optimisation improved PPRE purity by reducing the baseline emittance. Beyond readily-available diagnostics, we demonstrate how crystallographic diffraction can be used as a user-relevant method to characterise PPRE with statistically significant evidence of isolating a single excited bunch. Together, these methods provide a practical and user-orientated framework for synchrotron facilities considering similar timing-mode capabilities.
