As part of a broader effort to modernize beam diagnostics at SLAC, we are developing a new middle-layer application to support wire scan measurements using Python. This tool is designed to replace aging MATLAB GUIs with a streamlined framework that interfaces directly with EPICS and Beam Synchronous Acquisition systems. The middle layer manages the complete wire scan workflow while emphasizing modularity, reproducibility, and integration with existing controls infrastructure. This talk will cover the system architecture, practical implementation details, and lessons learned in deploying a diagnostic tool suited to the high-throughput, real-time needs of accelerator operations.
