Metrology for Run II at the Collider Detector at Fermilab (CDF) required a very complex geodetic survey. The Collision Hall network, surveyed with a Laser Tracker and digital level, provides a constraining network for the positioning of the Central Detector (CD). A part-based Laser Tracker network, which surrounded the 2,000-ton CD, was used as control for assembly. Subassembly surveys of the Detector’s major components were measured as independent networks using Laser Tracker, V-STARS/S [1] digital photogrammetry system, and BETS [2] theodolite triangulation system. Each subassembly survey was transformed into and constrained by the part-based network. For roll-in, the CD part-based network was transformed into the Collision Hall network coordinate system. The CD was positioned in the Collision Hall using two Laser Trackers in “stakeout mode.” This paper discusses the survey, adjustment, transformation, and precision of the various networks.
