Description
The APS Upgrade replaced the original storage ring with a fourth-generation multi-bend achromat lattice and modernized its accelerator controls while retaining the injector systems. The upgraded controls integrate a high-speed network, enhanced timing and event distribution, advanced beam diagnostics, and time-correlated data acquisition within the EPICS framework. These improvements enabled a rapid transition from decommissioning to beam commissioning and the restoration of user operations within one year. This paper summarizes the current status of the APS accelerator controls, highlights key system upgrades, and presents lessons learned that may serve as a reference for future control system modernization.
