Description

The Advanced Photon Source Upgrade (APS-U) represents the latest advancement in ultra-low emittance storage ring light sources. Since its commissioning and the commencement of user operations in 2024, APS-U has successfully reached its design beam current of 200 mA and operates reliably for user experiments. The diagnostic systems have been integral to the successful commissioning and operation of the machine. This paper presents the beam commissioning results of various diagnostic systems in the APS-U storage ring, with a focus on beam position monitors. Additionally, we will discuss various beam measurements, including beam current and lifetime, tune, beam stability, and swap-out injection bunch motion.
