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.
