Infrastructure B.180 Meeting #5

→ Europe/Zurich
Hide
  • First winding mock-up
    • All 3D-printed parts for the first winding mock-up are available
    • N. Lusa machined a short winding mandrel, in such a way that the spool has enough space to turn over the mandrel
    • Everything is ready to start the tests
    • Seb will prepare the winding machine (including spool). First winding tests on Wednesday 09/04/2025

 

  • Further winding tests:
    • BOND coil-end design accounts for only 20 mm distance in between the exit of the hard-way and the beginning of the easy-way bend.
      • In general, we try to ensure a distance of half the twist-pitch to improve cable stability
      • We propose to perform two winding tests with the geometry of the layer jump with 20 mm and 50 mm. Based on the results we will choose our final flared-end geometry.

 

  • Infrastructure and operation:
    • Jerome got the green light to go ahead with the offer from Siemens for the upgrade of the winding machine
      • He will send the offer. He will try to minimize the impact on the availability of the winding machine
      • The idea is to intervene and finish the work on the machine by the end of 2025
    • Jerome will also take a look on the possibility of using high-temperature capacitive sensors (or even LVDTs) in our ovens. He will check how to bring wires out (feedthroughs), the type of wires etc
      • He will ask for an offer for the capactivie sensors, in order to buy at least one and start trying.
