Resources on Technical Support  about 8 men/year in the last 7 months
(including Opening/Closing)

5. Opening & closing activities
Side A
Side C
1- Forward shielding craned to surface:
10 parts (65t to 97t)
2 trucks (55t each)
2- Big Wheels moved outward
Side A
Side C
3- Light trucks lowering and positioning
4- ECT movement

6. Opening & closing activities
ECTs, Small Wheels, End cap calorimeters are moved on air pads, with friction strength of 1-2%
Movement is controlled within a few mm, for objects from 100t up to 1000t.
Scaffolding are build in between detectors to provide access for users.
Full opening operation performed in 18 days, partially in 2 shifts
Side A
Side C

7. Opening & closing activities
The closing operation is always longer, in particular because of Forward region activities that slow down the process
7.5 weeks including the replacement of 15 TGC chambers on Big Wheels and EO gas leak repair
Careful positioning of Barrel Area detectors thanks to 2 methods
ADEPO = home made system based on Bcams (developed by Brandeis university)
Classic survey measurement
No correction applied in calorimeter software before the Run !
Difference in Y are caused by UX15 movement
Vertical alignment in between detectors is about 0.1 to 0.2 mm
Very efficient organization of cleaning of the Barrel Toroid
1 day with 8 teams in parallel

8. Support to detector installation
Intervention on ECT air pads
Temporary supporting of ECT (about 320 tons each!)
Replacement of air pads and air valves
BMG installation (in sector 13)
Tooling fabrication
Installation of 12 chambers
Removal/installation of BME on both sides
Access consolidation
Modification of S13 elevator
Frequent requests for change on calorimeter access
Support to CSC chamber repair
Access modification in real time

9. Support to infrastructure maintenance
Rack cooling
Hoses replacement (to be continued)
Sniffer maintenance
Module maintenance
Pipe cleaning and test
DSS maintenance and consolidation
LAr rack installation
Cabling
Completion of AFP
Replacing pneumatic pipes for gas system
Various cabling activities in USA15
Pulling of 3 cables in SDX1
Pulling one cable for LAr cryo from USA15 to UX15
44 cables for Ga-As detectors
Pulling 4 cables to cameras
Pulling cables from the TPX rack in USA15 to the device Timpix3 sensor
List is not exhaustive
