Abstract
A magnet structure including sets of permanent magnets installed periodically in a direction S with a spatial period λu, each set including a magnet of each of a first beam, a second beam, a third beam, and a fourth beam, the magnets of each beam being arranged in succession in the direction S, the first beam and the second beam being arranged in succession in a direction Z, the fourth beam and the third beam being arranged in succession in the direction Z, the third beam and the second beam being arranged in succession in a direction X, and the fourth beam and the first beam being arranged in succession in the direction X, wherein, for at least four successive sets of magnets with a spatial period λu, the magnetization vector of each magnet of each beam has a non-zero component in each of the directions X, S and Z.
