PPT-Outstanding Issues in Stave Core Assembly

Probably not a complete list Outstanding issues Bonding problems when gluing the top face sheet Observed in stave 12 M issing bond in area close to the EOS between the foam blocks foam blocks seem to be bonded and thermal FEA agrees.

Lynn (BNL), LBNL Mechanical Meeting, Sep 2012. 1. US Stave Fabrication Sequence. 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. Ian Wilmut .

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) . E. . Anderssen. , M. . Cepeda. , M. Garcia-. Sciveres. , M.
