Abstract
A floor, wall and ceiling construction for a magnetically shielded room which provides a stable and homogeneous magnetically shielded space or environment having an extremely high attenuation value while absorbing exterior as well as interior vibrations.
Claims64
A magnetically shielded room which rests on a substrate and has a floor including a weight bearing floor, a ceiling and a plurality of walls, said magnetically shielded room comprising:
- an exterior shell having an electrically conductive non-magnetic shield and a magnetically permeable shield, said exterior shell extending substantially throughout the floor, ceiling and walls;
- an interior shell having an electrically conductive non-magnetic shield and a magnetically permeable shield, said interior shell disposed within the exterior shell and extending substantially throughout the floor, ceiling and walls;
- and
- a plurality of separators which extend through and support the exterior shell and the interior shell and magnetically decouple the exterior shell and the interior shell by sufficiently separating the exterior shell from the interior shell, said separators including first non-conductive insulation members disposed between the exterior shell and the interior shell which dielectrically separate the exterior shell from the interior shell.

A magnetically shielded room which rests on a substrate, said magnetically shielded room comprising:
- an exterior shell having an electrically conductive shield and a magnetically permeable shield;
- an interior shell, disposed within the exterior shell, having a electrically conductive shield and a magnetically permeable shield;
- a weight bearing floor disposed within the interior shell;
- and
- a plurality of floor separators which support the weight bearing floor, extend through and support the exterior shell and the interior shell, each floor separator supports the weight bearing floor independent of the exterior shell and interior shell and dampens vibration from the weight bearing floor and the substrate which lessens deterioration of the attenuation characteristics of the interior and exterior shells.

- an exterior shell having an electrically conductive non-magnetic shield and a magnetically permeable shield, said exterior shell extending substantially throughout the floor;
- an interior shell having an electrically conductive non-magnetic shield and a magnetically permeable shield, said interior shell disposed within the exterior shell and extending substantially throughout the floor;
- and
- a plurality of floor separators including an exterior section extending through the exterior shell, an interior section extending through the interior shell and a spacer between and connected to the exterior section and the interior section, said exterior section, said interior section and said spacer co-act to support the weight bearing floor independent of the exterior shell and the interior shell and to dampen vibration from the weight bearing floor and the substrate, said spacer magnetically decouples the exterior shell and the interior shell by sufficiently separating the exterior shell from the interior shell, and said separators include first non-conductive insulation members disposed between the exterior shell and the interior shell which dielectrically separate the exterior shell from the interior shell.
