  • Magnetic system, particularly for ECR sources, for producing closed surfaces of equimodule B of form dimensions
    Patent number: 6194836
    Abstract: The invention relates to a device for generating a magnetic field {right arrow over (B)}, comprising a multi-pole structure (M1, M2, M3) in which the elements have polarities such that the vector sum of the fields created at each point by each of these elements is sufficient to define at least one closed line of minima B inside a surface with constant modulus (70) closed in the space. Application for an ECR source.
