DT Magnet Activities Overview FH 25/06/2010 -FH

Magnet Activities in DT
Three main activities M&O of LHC magnet Control Systems B-field measurements General Magnet Support Maintenance, Repair, consolidation of FT magnets Displacement of magnets (dismantling, re-assembly…) Stock of old magnets Construction of New Magnets -> Aegis Gert O. Felix B. 25/06/2010 -FH

Magnet Support Work In addition to the LHC magnets CERN has ≈ 38 experimental magnets In Operation Zones: 10 warm magnets 3 superconducting magnets Storage (B610 or outside) 19 magnets (partly in bad shape) DT use 4 magnets for sensor calibration and component tests. On loan UA1 magnet in J-Parc MNP21/2 in GSI The operation is mostly done by EN-MEF Most of the magnets are > 25 years old, and they are poorly documented. The repair and maintenance work relies on one or two experienced technicians; the people that were involved in the construction are all retired. In spite of a very valuable park of magnets, DT spends little (certainly too little) resources To maintain the magnets in good conditions To maintain the knowledge and expertise on the warm magnets Examples of recent Activities: Repair of COMPASS Magnet (water leak) Dismantling of NA60 Toroid Magnet Dismantling of NA62 magnet -> re-assembly in autumn this year Since 2008 we are missing a magnet Engineer, who follows this up. Successors from W. Flegel and M. Lossaso 25/06/2010 -FH
