Title (EN) MAGNETICALLY SHIELDED ROOM WITH INTERNAL ACTIVE MAGNETIC FIELD CANCELLATION, AND ITS USE
(FR) CHAMBRE A ISOLATION MAGNETIQUE CONÇUE POUR L'ELIMINATION DU CHAMP MAGNETIQUE ACTIF INTERNE, ET UTILISATION DE CELLE-CI
Abstract: front page image
(EN)The apparatus (50) includes an enclosure (24) having the wall (26) defining an interior and an exterior of the enclosure (24). The layer (52) of the highly magnetically permeable material is located closer to the interior of the enclosure (24) than is layer (54). The background field magnetometer (56) is positioned within the enclosure (24). An electrical coil structure (62) is made to provide the most complete cancellation of a particular background magnetic field.
(FR)L'invention concerne un dispositif (50) comprenant une enceinte (24) dont la paroi (26) définit un intérieur et un extérieur de l'enceinte (24). La couche (52) du matériau hautement perméable au magnétisme est située plus près de l'intérieur de l'enceinte (24) que la couche (54). Le magnétomètre de champ d'arrière-plan (56) est placé à l'intérieur de l'enceinte (24). Une structure à enroulement électrique (62) est conçue pour obtenir l'élimination la plus complète d'un champ magnétique d'arrière-plan particulier.
