Preparatory work for installation

• To prepare the positioning and alignment in HIE-ISOLDE area• Fiducialisation of the CM• Iterative process• Check by MATHILDE* System• To be completed by measurements under vacuum and cryogenic

Resources

• For each in-field task, a team of 2 surveyors needed

• Budget for industrial support planned (SU Contract) for HIE-ISOLDE Survey (LINAC, HEBT, Installation,…)

• Flexibility Minimum of 3 surveyors to be trained to work in Class 100 (To face LS1 priorities, Non-LHC Experiments survey work, …)

• Basic training of clean room technicians to survey Minimization of people in Class 100

• But… End of Marie Curie Fellowship in October 2014

Summary

• Survey work all along the process

• A lot of short tasks (typically 1 or 2 days each)

• Tasks identified and discussed

• Integrated (or being integrated) in the assembly procedures by Lloyd’s team

• Integrated (or being integrated) in the assembly planning

• SU Flexibility needed to follow the assembly step by step

• Co-activity possible but to be discussed case by case

• Time and resource for data analysis and reporting not to be forgotten

• Worrying: End of Marie Curie Fellowship in October 2014 …
