1. DT Magnet Activities
Overview FH

2. 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

3. 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
