  • Electromagnetic device for production of cold neutral atoms
    Patent number: 6548809
    Abstract: An electromagnetic device for producing cold neutral atoms having a ferromagnetic structure with four poles disposed in the same plane XOY excited by main coils (the quadrupole) supplying the main excitation, and two additional poles (the dipole) oriented along an axis Z and perpendicular to the plane of said four poles, the poles being magnetically coupled by one or more yokes.
