Alignment of production quadrupole magnets for the LHC interaction regions

Production has started for the high-gradient superconducting quadrupole magnets developed by the US LHC Accelerator Project for the Interaction Regions of the Large Hadron Collider. The first full-scale Q2 assembly has recently been measured during fabrication at Fermilab. This paper reports on the...

Description
Summary:Production has started for the high-gradient superconducting quadrupole magnets developed by the US LHC Accelerator Project for the Interaction Regions of the Large Hadron Collider. The first full-scale Q2 assembly has recently been measured during fabrication at Fermilab. This paper reports on the mechanical alignment processes used during production of the combined cold-mass assembly and during its installation in the cryostat, and the validation of these processes in meeting accelerator requirements. Also presented are the results of measurements of the field axis and roll angle of the completed magnet assembly. Results are compared to machine performance requirements.
