    Mechanical table assembly:

    • Cycling ongoing but under visual inspection for the moment

    TCC:

    • Leak on the rigid connection between test bench and tubes
    • Thermocouples arriving in 1 weeks
    • New screen to check with Paolo

    Design:

    • Jaw lifting tool produced by STI
    • Jaw and tank procedure to update in 4 weeks

    Absorber materials update:

    • Check the Carlotta’s attached document – Some work to improve the cleanliness of the process
    • CuCD blocks for first jaw S33 with 1 spare, rest of the blocks ready for S40 (blocks 4 and 5 relatively good)
    • Delays need to be checked

    VSC:

    • Waiting for costs and delays
    • Design modifications due to holes position : invert the male and female part because the pins are too long : ok for protos  
    • Check an arrangement between STI and VSC to order one time for all the components
    • 15th of July reception of jackets
    • Prod of autoregulated testbench for the serie

    BI:

    • EDMS 2419688 for the ABCD convention: same as CEM
    • A discussion is needed to check with CEM the viability of the proposition
    • ABCD stay fix and thanks to that we know which BPM is on which jaw and upstream or downstream

    Production:

    • Bellows on shaft end by Tuesday, then cleaning and FE end of next week, welding on tank in 3 weeks then leak tests
    • Tank waiting for FE, then FE for bellows assemblies
    • Jaw copper parts TCTPXH n.1 finished and the rest before the Fabrice’s holidays
    • Action for Dylan : give to Emilien which reference of RF finger to produce for tests and quantities
    • BPM flange at 40/30 for leak tests for the repaired ones, now only 1 leak, to be repaired
    • Manifold from STI almost done + lot of other parts

    Additional screws:

    • We now have 4x3 screws: Rollvis, Schaeffler, Ewellix, and maybe Moog

    Graphite tapering:

    Update on planning:

    Update for the serie:

    • Let the Combitac in the initial position for the serie
    • Update the leak test tool for bellow production for the serie
