Abstract

The LHC insertions are equipped with several different types of individually powered superconducting quadrupoles. These units comprise several quadrupole magnets and orbit correctors, and range in length from 5.3 m to 11.3 m. In spite of the variety of types and interface requirements, the design of the quadrupoles is based on the same principle where two welded half-shells provide the rigidity and alignment of the magnets and serve as a helium pressure vessel. In this paper we present the mechanical design of the LHC insertion quadrupoles, describe the initial experience in the assembly of the pre-series units, and report on the alignment measurements.
