Description
This paper presents an integrated three-component software suite developed at SLAC National Accelerator Laboratory for high-precision network measurement and adjustment in accelerator alignment. The system consists of AlignTrackPro for automated laser tracker data acquisition, a modernized version of the legacy LEGO adjustment engine, and LEGO Pipeline, which provides visualization through interactive 2D network maps and error ellipses. The suite addresses a critical limitation of commercial laser tracker software: the inability to perform gravity-compensated network adjustments. In large networks, neglecting gravity-field effects on measured height differences can introduce errors of approximately 0.2 mm over 50 m baselines, which is significant relative to the sub-millimeter tolerances required in accelerator facilities. The integrated system is now in production use for SLAC facility networks.
