Abstract: A variable-period permanent-magnet undulator which is applicable not only to a planar undulator but also to a helical undulator, in which permanent-magnets and ferromagnetic substances are alternately arranged, and the ferromagnetic substance interposed between the permanent-magnets is saturated to thus enable the magnets to be effectively spaced apart from each other by the repulsive force between the permanent-magnets, thereby adjusting the period of the magnetic field in an easy and precise manner.

Abstract translation: 一种可变周期永磁体波动器，其不仅适用于平面波动器，而且可应用于螺旋形波动器，其中永磁体和铁磁物质交替布置，并且介于永磁体之间的铁磁物质饱和 能够通过永久磁铁之间的排斥力使磁体彼此有效地间隔开，从而容易且精确地调整磁场的周期。
