Description
This report details the long-term settlement monitoring and local alignment adjustments of the Taiwan Photon Source (TPS) storage ring. Following successful adjustments in 2020 and 2021, the latest data (2024–2025) indicate a continuous settlement trend in specific areas, which will serve as the basis for future alignment planning. Additionally, to overcome line-of-sight obstructions caused by the shielding hutches of newly constructed experimental stations, the team tested a new approach involving the removal of ceiling shielding blocks to establish control network connections. Measurement results reveal that certain peripheral areas (e.g., the loading dock) undergo significant displacement due to seasonal temperature variations, further confirming temperature fluctuations as the primary source of error. In the future, establishing a new observation network can mitigate thermal interference and assist beamline alignment, thereby maintaining measurement reliability.
