Description
The In-Vacuum Tapered Undulator (IUT24) was developed for the Phase-III beamline project at the Taiwan Photon Source (TPS). To counteract strong, non-linear magnetic attraction forces while maintaining precise synchronization between magnet arrays, a robust motion control architecture was implemented. This system integrates an EPICS-based supervisory layer with EtherCAT field I/O and BiSS-C absolute linear encoders (50 nm resolution) in a closed-loop pulse command configuration. Experimental results demonstrate that during dynamic gap transitions, the tracking error is strictly maintained within ± 2.5 𝜇m, and inter-axial synchronization remains within 0.5 𝜇m. Furthermore, long-term position stability was measured at ±150 nm over 200 minutes. This paper details the hardware integration, advanced motion control strategies, and comprehensive performance evaluations that confirm the system’s readiness for high-precision beamline operations.
