Description
Fermilab’s PIP-II project will result in a new beamline approximately 550 meters long and will require establishing a geodetic control network to align all beamline objects in the tunnel. The first installation stage involves lower-precision alignment of objects such as stands and girders. The second installation stage involves high-precision alignment of beamline components. At Fermilab, a high-precision network is normally established at the beginning and is used for both stages for convenience. However, it was not possible to establish a high-precision network before the first stage due to construction delays. Instead, a preliminary network was established which allowed for speed and flexibility of implementation while still also delivering acceptable accuracy.
