Description
The LHC will be composed of 1232 horizontally curved, 15 meter long,
superconducting
dipole assemblies and 474 Short Straight Sections containing various types of
quadrupoles. These magnets are manufactured by several European companies and half
of them are currently produced. The field quality at room temperature is strictly
monitored to guide and validate the assembly at different stages of the production
in the industry. Dipoles and quadrupoles are measured with two different rotating
coil systems. Thes "moles" travel inside the 50 mm aperture and accurately measure
the field and gradient strength integrated over the length, the field direction and
high order harmonics. In this paper we describe these two systems, their
performance
and experience gained through the two first years of operation.
