High-field magnets
We use high-field magnets to investigate the properties of (new) materials. With these magnets, we can see into the matter without breaking anything. Many scientific insights once began with magnet research and the stronger the magnet, the more surprising the results. HFML-FELIX therefore has five magnets with a field strength of 30 to 38 Tesla and we are currently developing a hybrid magnet aiming at a maximum field of 45 Tesla.

General reminders
- Shifts include a 30 minute break for food.
- Keep track of the water temperature in the buffers (so the next group can use them).
- Always write down the He-level after Helium transfer.
- Write down changes on the whiteboard!
- Finish on time, clear your stuff and go home.
