Compression Testing

  • Stainless steel dummy testing has been completed.

  • Testing is now ongoing with the copper dummy.

  • The coil is currently in metrology and is expected to be returned next week or the following week.

  • Testing campaigns:

    • Universal testing machine setup with instrumentation mounted on top of the coil.

    • Manual setup with an observation window, allowing the coil to be visually monitored from above during testing.

Data Evaluation

  • Wrap-up of measurement setups used over time.

  • Current status:

    • Semi-automated measurement and evaluation pipeline implemented.

    • Measurement resolution is sufficient to detect deviations from nominal behavior.

4.2K Measurement Setup - Final Design

  • Final setup presented.
  • All pieces are in production with Jorge now. First pieces are being produced as we speak.

Grenoble Test (20 T Background Field)

  • Simulations performed at higher temperatures using the original pancake architecture.

  • Results indicate a temperature limit of approximately 40–45 K to reach the critical current.

  • Mechanical considerations:

    • Structural protection and casing are required. This includes:

      • An outer shell.

      • Internal support to withstand both inward and outward forces during cooldown and ramping of the background magnetic field.
