Strong permanent magnet-assisted electromagnetic undulator
This patent describes an undulator wherein electromagnet poles are located along opposite sides of a particle beam axis normal to the beam axis with alternate north and south poles on each side of the beam to cause the beam to wiggle or undulate as it travels generally along the beam axis, the improvement which comprises reducing the saturation of the electromagnet poles by the use of permanent magnets spaced in between adjacent electromagnetic poles on each side of the axis of the particle beam in an orientation wherein the north and south poles of the permanent magnets are parallel to the particle beam axis and normal to the magnetic axes of the electromagnetic poles to reduce the saturation of the electromagnets to thereby permit the increasing of the field strength of the electromagnets beyond normal saturation levels.
