    Update from N.Peray:

    ENDPLATE:

    • The chosen option for the rod has been integrated in the model. 40 mm diameter rod with M42 thread
      • This requires shifting the hole position as already seen.
      • Minimum threaded length computed
    • The required shift can be minimized using custom components (Slide 5)
      • For this custom design, the minimum thickness of material is today 2 mm
      • Action item: Move it further by 2 mm to gain 2 mm in radius all over the hole in the endplate minimum thickness (in any case we showed in the past that even 7 mm shift was not an issue)

     

    YOKE-SHELL:

    • Yoke and shell:
      • Flat surface added on top of the yoke for easier assembly (introduction inside the shell)
      • Tolerances need to be updated in such a way that accounting for tolerances, the maximum of the yoke is always less or equal than the minimum of the shell.

     

    DUMMY COIL:

    • Real ground insulation layers will not be used in the dummy assembly. Just one kapton layer wrapping the coil.
    • Action item: Check 2D ANSYS and define the Aluminum allow required
    • Pole instrumentation shall be included (strain measurements as in the real coil)

     

    ENDPLATE APERTURE:

    • Diameter of the aperture in the end-plate? 
      • We must find a way to make it co-axial with the magnet aperture
      • We should make it a bit bigger (52 , 54 mm)
      • Add threaded holes to fit an interface piece that fits the magnetic shaft with the aperture through the loading plate

     

    UPDATE ON MOCK-UPS:

    • Nico got the poles and the plates back from the main workshop
    • Winding of the mock-up tomorrow
    • Gaps to be introduced:
      • 4 mm for pole gap
      • 8 mm for tooling gap
    • By the end of this week, the mock-up must be in B.112 
      • RHT cycle to be launched on Friday ideally

     

     

    SIMULATIONS TO DO:

    • Final endplate workbench simulation
    • ANSYS simulation of the dummy coil case (2D and 3D ideally)
    • Check E-RMC aluminum dummy case (Jose)
    There are minutes attached to this event. Show them.
