本文提出了一种新的波荡器，用于产生双偏振辐射。该波荡器由电子轨道平面上方和下方的两对平面永磁体阵列组成。该波荡器的磁场通过移动磁体阵列对的相对位置来诱导螺旋或正弦电子轨道运动。它导致产生圆偏振或线偏振波荡器辐射。
A new undulator is proposed for generating variably polarized radiation. This undulator consists of two pairs of planar permanent magnet arrays above and below the electron orbit plane. The magnetic field of this undulator induces helical or sinusoidal electron orbit motion by shifting the relative positions of pairs of magnet arrays. It leads to the generation of circularly or linearly polarized undulator radiation.
