摘要： A multipole magnet for deflecting a beam of charged particles, comprising a plurality of ferromagnetic poles arranged in a pole plane, and a plurality of permanent magnets arranged to supply magnetomotive force to at least one of the plurality of ferromagnetic poles to produce a magnetic field along the pole plane in a beamline space between the poles. The multipole magnet further comprises a plurality of ferromagnetic flux conducting members arranged to channel magnetic flux from at least one of the plurality of permanent magnets. At least one of the plurality of permanent magnets and the plurality of ferromagnetic flux conducting members is moveable in the pole plane relative to the plurality of ferromagnetic poles so as to vary the strength of the magnetic field in the beamline space. The multipole magnet is a quadrupole magnet comprising four ferromagnetic poles and two permanent magnets, wherein each of the two permanent magnets is associated with two of the poles to supply magnetomotive force thereto.
