Controlling Field Quality in Magnet Production

The field quality measurements at room temperature of around 100 collared coils of the main LHC dipoles are analysed. Using correlations to field measurements at 1.9 K, comparison with beam dynamics limits are discussed. Both random and systematic components are analysed, allowing to pin out the mos...

description The field quality measurements at room temperature of around 100 collared coils of the main LHC dipoles are analysed. Using correlations to field measurements at 1.9 K, comparison with beam dynamics limits are discussed. Both random and systematic components are analysed, allowing to pin out the most critical multipoles. Corrective actions that have been taken during the pre-series phase are presented; we focus on the low order systematic multipoles that are shown to be the most difficult components to steer. A preliminary analysis of the integrated main field and of its implications on the possible scenarios for the installation are also carried out.
