  1. Clic Vertex Studies 01/21/2014 François-Xavier Nuiry Wolfgang Klempt Fernando Duarte Ramos Miguel Angel Villarejo

  2. NEXT STUDIESStave prototypes present at CERN THERMAL STUDIES Finalisation of thermal tests with full sandwich prototype (NIDA Core). First comparisons with simulations. Thermal tests with full sandwich prototype (ROHACELL Core). Same boundary conditions as before. Comparisons with simulations. Additional studies of the stave temperature gradient with IR camera Upgrade of the set up (Purchase of AMTIR material:amorphous material transmitting infrared radiation). Data acquisition with IR camera Comparison with Simulations

  3. NEXT STUDIESStave prototypes present at CERN STAVE MECHANICAL STUDIES Comparison with the MECHANICAL MEASURMENT LABORATORY (EN dept.) 3 points bending tests with same span (180mm) Conclusion concerning stave flexural stiffness measurements Vibration studies (laser sensor) of full sandwich staves Set up upgrade ongoing (new plateau + sensor support) Measurements could be done mid / end of February

  4. NEXT STUDIESNew stave prototypes Design and simulation work…then prototyping Simulation of lattice staves done with a new technique (pre-moulded skins) Simulation and prototyping of new full sandwich staves (New materials, NTPT collaboration, etc…) Simulation of filament winding staves

  5. News Arrival of a new Engineer (1/02/2014, VIA program) in PH/DT. -Main role: setting up a laboratory dedicated to composite prototyping and characterisation. -Collaboration with ALICE experiment. -Collaboration with CLIC vertex studies. Work description (proposal): Francois Boyer will be asked to realise different type of prototypes within the CLIC VERTEX detector project. Several techniques are studied: standard sandwich structures, filament winding, very thin prepreg implementation. Here is the list of the proposed activities: -Material procurement (Prepreg, simple fibres (3K, 6K, etc.), resin, core materials, tools). -Setting up a material library. This library would be a database of fibers, resins, prepregs, and core materials suitable for the vertex detector. -Stave prototyping (different designs proposed). This R & D activity can be done in collaboration with other experiment (ILD), institutes/universities and companies (TPT, Composite design, etc...). The manufacturing developments of filament winding staves prototypes will be asked. The manufacturing improvement of full sandwiches and open sandwiches staves will be proposed in order to get small productions with qualities close to industrial standards. -Specific tooling used for the prototyping (design with Catia / Ansys ACP and production follow up) -Prototype characterisation Measurements of flatness, dimensions, mass, flexural stiffness, torsional stiffness, and eventually X0 are the minimum characteristics needed for each prototype. Supervisors: Francois-Xavier NUIRY and Fernando DUARTE RAMOS.
