CCT R&D meeting #1

Europe/Zurich
Attendees: Helene Felice, Ariel Haziot, Glyn Kirby, Davide Tomasini
Presentation draft plan by AH
- Mains technological choices to make before D1.
- Requirements for these choices.
- DT notices that "no cracks" is not appropriate for wax. HF proposes "Minimize energy realease during cool down"
- Discussion on a different strategy for magnet design: something that remains all the the time under compression, releasing stress on the former. The former is supported by the outer rim. For example a liquid that expends when cooled down
- Necessity of a 2D model and FEA
- Description of the winding test
- Cabling machine used for Hi-lumni CCT is weak according to FOP, opportunity to improve it.Desc
- Description of the impregnation test
- A small coil test is still important. The box test is not so representative. Small amount of cable 1km instead of 9 for D1.
- Description of the cheap field laboratory
- The small CCT idea gets some good feedback as it can start almost now.
- This program is important and should be ran in parralale to the small tests for D1
Presentation design ideas by GK
- Design of combined function with only few turns.
- 2 layers, 8 turns, 200 mm aperture, still almost 4T peak field
- 2 layers, 4 turns, 200 mm aperture, around 2T peak field
- what about 2 turns ?
- what about 2 turns and 50 mm aperture ?
- ...
Other discussion
The GRP former, what should we do with it? It is proposed to use it to do small coil test on GRP formers. Maybe design a step file with the path for 2 coils with 2 layer on the full length. We will slice it afterwards.

- GK will prepare some more designs, specially for the small CCTs
