Description
Achieving and maintaining the alignment tolerances required for the upgraded Advanced Photon Source (APS) is a significant challenge, particularly in the presence of ground motion and settlement. To monitor vertical displacement and transfer elevation over long distances, two hydrostatic leveling systems (HLSs) are being deployed at APS.
The storage ring system consists of 105 HLS sensors designed to characterize both relative floor motion at each insertion device front end and global floor motion throughout the storage ring tunnel. A second system, comprising 2 HLS sensors, is being implemented to transfer X-ray source-point elevations to the Long Beamline Building (LBB), approximately 200 meters away.
This presentation will describe the design and intended application of both systems and summarize the current status of their deployment. As neither system is fully operational, we welcome discussion and feedback from attendees with experience in commissioning and using similar systems.
