    Abstract: A magnetometer (20) is prepared by depositing three thin-film SQUID magnetic field detectors (26, 28, 30) upon a substrate (24). Two of the detectors incorporate stripline SQUID detectors (26, 28) deposited at right angles to each other, to measure the orthogonal components of a magnetic field that lie in the plane of the substrate. The third detector uses a planar loop SQUID detector (30) that measures the component of the magnetic field that is perpendicular to the substrate. The stripline SQUID detectors have thin-film base (42) and counter (46) electrodes separated by an insulating layer (50) which is at least about 1 micrometer thick, and a pair of Josephson junctions (52) extending between the electrodes through the insulating layer.

    Abstract: A magnetometer includes a support having two support surfaces that intersect each other along an intersection line that is perpendicular to a reference axis of the magnetometer. The support surfaces are preferably perpendicular to each other and are each inclined at an angle of 45 degrees to the reference axis. A planar sensor/detector array is mounted on each support surface. Each array includes at least two pairs of magnetic field sensors and associated SQUID detectors arranged such that the magnetic field sensors lie on a line that is parallel to the intersection line of the two support surfaces. The magnetometer can be used adjacent to a surface to measure components and spatial variation of the magnetic field near the surface, with the measured components resolved into the magnetic field vectors parallel to and perpendicular to the surface.

    Abstract: A SQUID package includes a layered SQUID base (24) and a SQUID (22) mounted upon the base. The SQUID base is formed as a first substrate layer (30) of an electrically insulating material, a shielding layer (28) of a material that is superconducting at the SQUID operating temperature overlying the first substrate layer, and a second substrate layer (26) of an electrically insulating material overlying the shielding layer. The shielding layer protects the SQUID from dc and ac interference such as magnetic and electrical fields, which would otherwise interfere with its operation.

    Abstract: A shielded room (20) is constructed by mechanically attaching electrically conducting facing sheets (32) to the beams (30) of a frame in a manner such that there is a continuous electrical current flow path (44) between the facing sheets. The mechanical interfaces in the current flow path are sealed with a layer of copper or zinc (34) at the interface, the copper or zinc layer being preferably applied to one or both of the pieces that meet at the interface by a spraying technique such as plasma spraying. The copper or zinc connector seal ensures a continuous current flow path along the length of the mechanical interface, and prevents leakage of electromagnetic energy into the interior of the room. A magnetic field barrier such as sheets (48) of mu-metal can be supported on the assembled structure. The room (20) is readily assembled with mechanical fasteners (42), which permits it to be later disassembled and moved if necessary.

    Abstract: Boîtier d'interféromètre quantique comprenant une base d'interféromètre quantique (24) constituée de plusieurs couches et un interféromètre quantique (22) monté sur ladite base. La base d'interféromètre quantique est constituée d'une première couche de substrat (30) réalisée dans un matériau électro-isolant, d'une couche de blindage (28) composée d'un matériau qui est supraconducteur à la température de fonctionnement de l'interféromètre quantique et qui recouvre la première couche de substrat, et d'une deuxième couche de substrat (26) formée dans un matériau électro-isolant, qui recouvre la couche de blindage. Ladite couche de blindage protège l'interféromètre quantique des interférences du courant continu et du courant alternatif, telles que les champs magnétiques et électriques, qui sans cette couche de blindage gêneraient son fonctionnement.

    Abstract: On fabrique un magnétomètre (20) en déposant trois détecteurs de champ magnétique à interféromètre quantique à mince film (26, 28, 30) sur un substrat (24). Deux des détecteurs comprennent des détecteurs à interféromètre quantique à microbande (26, 28) déposés à angles droits l'un par rapport à l'autre, destinés à mesurer les composantes orthogonales d'un champ magnétique se trouvant dans le plan du substrat. Le troisième détecteur utilise un détecteur à interféromètre quantique à boucle plane (30) qui mesure la composante du champ magnétique qui est perpendiculaire au substrat. Les détecteurs à interféromètre quantique à microbande comportent une électrode de base (42) à mince film et une contre-électrode (46) séparées par une couche isolante (50) dont l'épaisseur est au moins égale à environ un micron, ainsi qu'une paire de jonctions Josephson (52) s'étendant dans la couche isolante entre les électrodes.
