    MINUTE 44

    Mechanical table assembly:

    • Cycling test launched
    • First torque test under load done and good

    TCC:

    • All the circuit are working well, automatic cycling to do
    • Specification ongoing
    • Check for design modification and cleaning of the posing surface
    • Carlotta performed a first model, Ansys benchmarking ongoing to launch new simulations. What is important is to confirm the parameters of the first analysis and the parameters that have an influence on the results. But also find a characteristic time mini acceptable with the TCC

    Design:

    • Jaw lifting tool designed and to be produced by MME
    • Jaw and tank procedure ongoing

    Absorber materials update:

    • CuCD blocks under metrology because new thermal treatment, impedance has to check if the porosity is a matter for them. Sent back 2 (or3?) blocks because parallelism not acceptable (70um, 60um), report attached to Indico

    VSC:

    • Waiting for costs and delays
    • Check the quantities needed: 2 total assembly + 4 bottom parts to be bought by STI
    • Design modifications due to holes position – 3D to be sent to Luca beginning of next week
    • Jacket ordered with ions pump: 6kCHF

    Production:

    • Shaft on Monday from TT, then last machining step
    • Contouring tank plate done
    • RF contacts welded almost all the references
    • First batch of jaw parts sent to STI
    • Beam pipes cut, then welding and carbon deposite
    • BPM flange at 40/30 for leak tests for the repaired ones, now only 1 leak, to be repaired
    • Cooling pipes ok even with 0.2mm of flatness on the border. Brazing next week
    • Cu parts 1 month left with priority on TCLPX parts to begin assembly before, but staff absent and CNC fail, need to be repaired

    Additional screws:

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

    Graphite tapering:

    • Metrology good, but not for 28.9mm of height, and this is quite ok for impedance
    • A gap of 0.05mm for the serie is not mandatory
    • A quotation of 4 more is sent to Graphitech

    Update on planning:

    Update for the serie:

    Others:

    • RGA final report almost done
    • Tools for flatness measurement: check the compatibility (point 4 or 132)
    • Production of 4 jaw lifting tools for STI and VSC
