Description
The Advanced Light Source at Lawrence Berkeley National Laboratory operates over 30 beamlines, most controlled by LabVIEW-based systems developed independently over decades. Project ACCORD (ALS Computing, Controls & OpeRations for Data) is a multi-year effort to transition these heterogeneous controls to a standardized EPICS-based architecture. Our strategy begins at the device layer: we replace legacy controllers with standard hardware (e.g. Galil), generate EPICS IOCs from a centralized device configuration database, and expose process variables to the existing LabVIEW UIs via PVAccess, allowing beamline staff to continue operating familiar interfaces while the control backbone changes underneath. Virtualized beamline computers enable parallel testing and safe reversion. We describe our phased approach, the automation tools that make facility-scale conversion tractable, and early results from pilot beamlines, with major deployment planned during the ALS-U dark time beginning in 2027.
