Description

The magnetic field of the LHC main dipoles must satisfy tight beam dynamics specifications to ensure good performance of the machine. After recalling the main features of the multipolar expansion of magnetic field, we summarize the specifications from beam dynamics and describe the corrective actions to improve field quality on prototypes and pre-series magnets. Magnetic measurements are also a powerful tool to control and follow up the production: we discuss how holding points have been organized and what critical cases have been found.
