6.3 Troubleshooting Work
6.3.1 After a Quench
Quench while in persistent mode:
1. Wait until helium stops evaporating and the quench valves are closed.
2. Wait until there is no helium vapor visible anywhere to make sure there is sufficient
oxygen in the room.
3. Check that the globes in the quench valves are in the correct position.
4. Remove probe and shim system to prevent formation of ice on the shim system.
5. Start the refill with liquid helium as soon as possible.
6. Contact Bruker Service immediately.
Figure 6.1: Magnet system during a quench
A quench is the very fast de-energizing of
the magnet by loss of its superconductivity.
The stored magnetic energy is converted
into heat, which promotes rapid evaporation
of large quantities of helium.
If a quench occurs contact Bruker Service
immediately.
