PPT-Stave Assembly (A random walk through stave construction)

Outline I got asked to think of specifications for module mounting system build accuracy I think the intention was to try and review where to use build tolerances stave module placement stave placement cylinder placement .

Differs mostly from UK sequence in that we pre-machine foam and make foam-pipe assembly. Do we need identical standardized assembly of stave core in production?. Tim. (25/9/14). Purpose of This Meeting. First meeting dedicated to discussing how we will determine if staves manufactured during production will meet the performance specifications required for operation in ATLAS.
