1 IBL Integration Activities & Future plans  Overall FEA on Geneva (in convergence with Seattle)  News from IST Composite Design  Integration jigs and related pieces  2011 schedule Impacts / 2013 Schedule University of Geneva: G.Barbier, F.Cadoux, A.Clark, D.Ferrère, C.Husi, M.Weber

2 Overall FEA… Simplified STAVES  CAD model: IST and Beam pipe not shown FE model: IST hidden for clarity…  FE Model: STAVE as shell (sandwich material) The goal is to have comparison with other FE models …as for the Stave program End ring Middle ring Service loads…

3 Overall FEA… Simplified STAVES  Boundary conditions (BC’s) between IBL and PIXEL BC Blocking / 1 end of Beam Pipe… the opposite one is free! Free? Bellows… Inner links between IST and BP IST: 6600mm long, K13C fiber at [0,20,-20,90,90,-20,20,0] 1G

4 Overall FEA… Simplified STAVES  Preliminary results show NO issue / BP sagging and IBL sagging Overall sagging: 350 microns on BP IBL region IBL region…seems very stable! Colin’s FEA (max deflection): 287 microns FEA from Geneva: 350 microns …as a first comparison! No fine tuning between models so far…  Need tests on IST proto for correlations

5 Overall FEA… Correlation works to be done soon!  Tests and FEA’s on a first IST prototype (short sections from Composite Design) IBL region Proto sent to CERN for Mock up (M55J fiber) T300 prepreg Tests LAPP (thanks to Pierre!) on:  T300 proto (0,6mm thick)  M55J proto (0.5mm)  FEA gives: 1.5mm for 30N applied  Test gives: 1.5mm for [25-28N] …about 10% difference! Testing to be done soon to check bending stiffness (on longer proto!)

6 News from IST Composite Design Based on the first mandrel (1m long) …which leads to 870mm long IST first!  Check the surface quality (as seen it’s good… to be measured / Peek pieces)  Check the circularity and dimension (ongoing at CERN metrology)  Comparison between T300 and M55J fibers (done)  Validate the whole process and de molding (quite easy!) The mandrel Prepreg wrapping Before extraction In the autoclave (IST in upright position!)

7 News from IST Composite Design Next steps on IST prototyping work:  Challenge is to go to 2200mm long IST segment (3 segments to get to 6600mm IST)  Needs to work on junctions (including the gluing, centering to guarantee straightness…)  2500mm mandrel to be manufactured (  85mm / h8 precision) + other mold for junctions  Start with one segment…then go step by step (1 junction after the other) Quotation on has been received from Composite Design (order will be placed soon … still need to get a metrology from CERN) junction Working in parallel development with Seattle is necessary (sharing of experience to get to the final results…)  Seattle is dedicated to K13C prepreg for IST and shielding foil lamination on IST (final unit)  Composite Design is a back up solution and provides protos, dummy IST for mock up, and half pipe for Integration stand and Beam pipe container (no VHM fiber here!) Gluing

8 Stave jig Jig schedule in 2011: -1 prototype to test all the steps in 2011 (in aluminum, May 2011) spares to come later (beginning of 2012) Jig schedule in 2011: -1 prototype to test all the steps in 2011 (in aluminum, May 2011) spares to come later (beginning of 2012) Loading tool Integration jigs and related pieces Former design as shown by Didier Latest design according to Stave new design To be interfaced with … Central body: 1300mm 3 fixations over the stave length… to be checked in the wire bonding process Middle point

9 Stave jig Integration jigs and related pieces Pin for location M1.6 or M2 To get access from below Central pin (with clip)

10 Support frame Half pipe as a rotating cradle STAVE driver PRELIMINARY STUDY Main concerns (Integration stand for Integration onto Beam Pipe) Beam pipe Container made of dummy IST’s  Milestone: beginning of 2012 to save time for testing…means 1 year from now (only 6 months for development!)…Gerard will re start in March 2011, BUT it’s tight! A common development with Grenoble has been identified here 7m long is mandatory at this stage

11 Integration activities Summary of 2013 Schedule Target: Early 2012 to start training, tuning,… Beam pipe container Composite design) 1 Validation on Stavelets Early April 2011 to validate the principle and launch a longer jig 2 Going to Stave0 length (Based on official design…no turning back) 4 3 June-July 2011 (to start loading on Stave 0) Could be used and checked for Heater Need earlier! Linked to IST development (April-May 2011) and Grenoble interfaces Stand design and fabrication Stave mounting system May be need of Dummy Bpipe?

12 Last but not least… IBL Support Structure REVIEW coming soon… When ? On March, 24 this year Where CERN Who is involved ? Marzio, Heinz, Giovanni, Raphael, Franck, and the reviewers among: - Ray Veness - Mark Gallilee - Neal Hartman - Eric Anderssen - Antti onnela - Ian Wilmut The goal of the review is to: - Sign off the IBL layout, envelops and interfaces - Confirm interfaces to the beam pipe - Review and go-ahead for support structure elements (IST, support rings,…) - Review of integration and installation tooling concept Still need to define to which level of details do you want us to go…time is short!
