Description
The Canadian Light Source has been operating its 2.9GeV storage ring since 2005. Beam-based metrics, primarily radio frequency tuning and orbit correction, provide a continuous, indirect measurement of the beam’s length and indicate a decrease in the storage ring beam circumference over time. The 171m storage ring is equipped with a 155-point wall and floor network to allow location of laser trackers for precision alignment and has been regularly surveyed to update the reference network. Recent and historical survey data is compared with beam metrics and we highlight key sources of discrepancy, including thermal variations, mechanical settling, and systematic survey uncertainties.
