Description
Final alignment measurements of the LHC low-beta quadrupoles are performed at
Fermilab, both for magnets fabricated in-house, and for cold-masses supplied by KEK
and subsequently cryostatted at FNAL before shipment to CERN. This talk reviews the
various measurements performed during production and during room-temperature and
cryogenic magnet testing. Results of determining the 6-axis alignment (x, y, z,
roll, pitch, yaw) of the one-element (Q1, Q3) and two-element (Q2a, Q2b) magnet
assemblies and their corrector packages are presented with a discussion of the
techniques and challenges involved.
