Beamline controls experiences under the APS upgrade project

The upgrade of the Advanced Photon Source included the design and construction of eight brand new beamlines and significant reconstruction of an additional fifteen existing beamlines. With such a significant amount of new support being required, the APS Beamline Controls group took the opportunity to evaluate the hardware we were using and the ways in which we develop and deploy beamline support. This is an overview of the outcomes of those discussions, alongside lessons learned during the actual implementation of such planning. We discuss the hardware chosen, changes in IOC configuration and management, support development challenges, and the setup of data acquisition to fully take advantage of our new beam.
