IBL Stave & loading tools

University of Geneva: G.Barbier, F.Cadoux, A.Clark, D.Ferrère, C.Husi, P. Iacobucci, M. Weber

The main goal for today…

Review and Validate the SPECS for the Staves (dim., tol., …and the related fabrication processes and tools) Review of the Assembly tools (Flex, Modules) and related SPECS Define the critical envelopes and the way to check them… Define the Services assembly at PP0 area (including Cable saver)

Proposed AgendaGeneral INTRO …15’ (Didier, Franck)

• Stave Fabrication and Assembly status… 30’ (Eric, Charlie)

B. Stave drawings + Assembly views onto Beam pipe… 30’

(Didier L, Christophe)

C. Stave Metrology @ CPPM and UNIGE …30’ (Eric, Didier?)

D. Flex on Stave …30’ (Francois-Xavier, Christophe)

……………………………Lunch Break……………………………

E. Overview on FEA applied to 14 Staves …20’ (Raphael)

F. Module loading on Stave …45’ (Coralie, Maarten, Didier F, Franck)

- Handling frame(s)

- Cradle(s) for loading

- Interfaces to Wire bonding and Pull tester machines

250mm

Extensions for PP0 + Cable savers

To be re machined afterassembly onto the CFRP profile

Mold to get the CFRP profile(thickness to be optimized)Outsourced…

Stave Tooling version #0 Stave Handling Frame (IBL_HF#0)

250mmFrom the U shape aluminum profile …to a CFRP rectangular shape T300 fiber, 25 units to be fabricated in 3 parts Max length is 1,5m

Flatness, parallelism, precisiongiven by the aluminum mold

Stave Tooling version #0 Handling Frame + Cradle #0

Bare Stave with Flex+Wings… Handling frame to be delivered to CERN for Flex assembly All the wings to be folded back for module loading Wing repositioned after modules are loaded and visual inspection done

Flex wings

NOT SHOWN HERE:Additional V support underneath the Stave Omega (x2)Used for Module loading and Wire bonding processes

AS received at UNIGE from CERN

Stave Tooling version #0 IBL_HF#0 (Access from the top)

Cutting out thru the CFRP profile

Close up… as seen from the top

15

Stave Tooling version #0 IBL_HF#0 (Other Integration issues)

PP0 support to be worked out(for final integration purpose) Avoid interference / neighbor Allow easy removal when stave in position
