Planning details
Specific solutions are possible in special cases for achieving load distribution in existing build-
ings. These solutions should be analyzed in relation to their vibration behavior. Discuss the sit-
uation and possible counter-measures with the planners from your local Bruker BioSpin MRI
office.
6.4.2 Magnet foundation
The ferromagnetic density should not exceed 100kg/m
2
in the area of the magnet foundation. If
this limit cannot be maintained for new buildings, non-magnetic reinforcement materials (e.g.
high-yield austenitic steels) should be considered.
The magnet foundation must be constructed in the form of a bonded screed. If an HF shielded
room is used, the bonded screed must extend at least over the surface area of the box.
Construction of the magnet foundation, if the original floor construction at the magnet installation site is based on a floating floor.
