| Title | Real-time EPICS-integrated RAON timing system enhancements |

| Abstract | The timing system of the RAON accelerator is critical for precise beam synchronization and safety interlocks. We present a real-time analog feedback infrastructure combining the Digilent ADP3450 (Zynq-7000) with a Raspberry Pi 5, enabling streaming and processing of >10 MSPS event data over the EPICS network. Beam frequency and pulse-width monitoring at sub-microsecond resolution are now directly available in the CSS Phoebus GUI. We have implemented and validated four key features: pulse train, ramp-up, optional emergency-halt, and event-switching. Testing demonstrates stable data delivery and responsive feedback control for 1 Hz signal adjustments and up to ~1 MHz sampling rates. These enhancements address limitations observed during 2024 operations, significantly improving safety, flexibility, and efficiency for upcoming high-energy beam delivery at RAON. |
