20. Two Paths to Precision: Laser Tracker and Photogrammetry for PETRA IV Magnet Fiducialization (TUO13)

Jana Barker (DESY)

High-precision and efficient magnet referencing is required for the series
fiducialization of the large number of multipole magnets for PETRA IV.

To meet the required precision while keeping the measurement process suitable for series production,
a high degree of automation is necessary.
Two concepts for relating external magnet fiducials to the magnetic axis
measured with a vibrating...

21. The fire incident in 2026 and interim solutions for the GSI facility (TUO14)

A major fire on 5 February 2026 in the RF Gallery at GSI almost completely destroyed the installation and equipment parts of the existing facility. This fire had such serious consequences that beam operations at GSI – and consequently the First Beam Event for the new facility FAIR – could not take place. Soon after the fire, initial ideas and discussions emerged on how to enable adequate...

22. Establishing the PIP-II Preliminary Control Network (TUO15)

David Krawczuk (Fermi National Accelerator Laboratory)

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...
