Description
Undulators at BESSY II are routinely inspected for their impact on the machine tune and orbit, with the goal of ensuring tune and orbit feedforward tables remain fit for purpose. In particular this is necessary following modifications to the storage ring, as well as more obvious cases such as the installation of new devices and repositioning of existing devices. To that end a commissioning framework exploiting the Bluesky ecosystem has been established. Undulators and diagnostic hardware are represented through Ophyd device abstractions, and measurements are orchestrated as Bluesky plans with full metadata stored in a mongodb database with databroker. This has enabled the creation of an ID scan dataset for real time analysis during commissioning, rather than relying on post-hoc extraction of data from the Archiver for offline analysis. This work has also brought more consistency and better reproducibility of undulator scans, and provides the infrastructure required for more ambitious commissioning goals. It has also brought flexibility to commissioning scripts to take advantage of other innovations on the BESSY II machine and control environment. This paper outlines the application of this work to routine undulator commissioning and future goals to further simplify commissioning workflows.
