    Update from Nico P.

    • Working on lifting and handling tooling.
    • Some orders still to be placed (BOM documents are ready). Juan will prepare a technical spec. and try to manage the procurement :
      • Impregnation mold
      • Reaction to impregnation transfer
      • Coil components
    • Waiting from Sylvain's feedback on instrumentation

     

    Update from Dimitrios:

    • Finished the 2D/3D for the bullet system.
      • We need to produce drawings to machine a pair of each bullets and bring them to EN-MME
    • Drawings for the endplate and rods missing. For the moment in stand-by (see below)
      • Decision to consider non-symmetric ends: on lead end-side the plate will not have the opening for the bladders. In non-lead-end side the plate will not have the opening for the leads.
      • Action: Dimitrios to prepare a model of the connection and non-connection side (with the current thickness). Jose to simulate it. Based on results, we optimize the thickness. We expect to gain a bit.
      • To be prepared right away.

     

    Update from racetrack mock-ups:

    • Actions:
      • Contact Oscar to check if he can provide preliminary results for the second DIC.
      • Wrap-up slides to be prepared for next week (Nico and Jose)
    • Previous mock-ups:
      • Pole: From 2 mm to 0.8 mm (closing by 1.2 mm)
      • Molds: From 4 mm to 2.88 mm (closing by 1.12 mm)
    • Third mock-up:
      • Pole: From 4 mm to 2.8 mm (closing by 1.2 mm)
      • Molds: From 8 mm to 6.8 mm (closing by 1.2 mm)

     

    Update from Nico B.:

    • No much advancement in the measurement / machining system. Jerome is pretty busy
    • Rather working in the assembly table, trying to use as much as possible what we already have
    • Bladders to be tested and production launched (Nico B. has a sample of the longitudinal welded tube)

     

    Update from Vendela:

    • 3 responses from different vendors
      • WMH Group
        • 7075-T7351
        • 7010-T7451
        • 7050-T7451
      • Aksel
        • 7075
      • Allega
        • EN-AW-7022
      • AXEL Al-7075
    • Vendela will ask for the material properties and then choose a candidate. The candidate will be characterized at CERN at cold.
