Description
A high-precision, bunch-by-bunch (BbB) synchrotron phase detection system has been developed and successfully commissioned at the Taiwan Photon Source (TPS). Designed to characterize complex beam dynamics and longitudinal filling patterns, the system operates across both the booster and storage rings. By leveraging digital in-phase and quadrature (I/Q) demodulation, the architecture systematically suppresses direct-current (DC) offsets and quadrature phase errors inherent in conventional analog schemes, achieving synchrotron phase extraction and filling pattern measurement at a 3 Hz repetition rate. The resolved BbB data are seamlessly integrated into the accelerator control framework for real-time visualization. This robust digital diagnostic framework provides the necessary precision to investigate transient beam loading and multi-bunch instabilities, establishing a critical tool for advanced beam physics studies in third-generation light sources.
