8 字形波荡器是 SPring-8 提出的一种插入装置 (ID)，用于减少普通线性波荡器遇到的热负荷问题。当 K 值较高时，为了获得低能光子作为波荡器辐射的基础，该装置非常有用。因此，它被采用作为 SPring-8 软 X 射线光化学光束线 (BL27SU) 的 ID，因为该光束线上的实验需要 100 至 2000 eV 之间的线偏振光子。 BL27SU 的 8 字形波荡器目前正在建造中，在第一阶段运行中，预计将覆盖低至 500 eV 的能量范围。在第二和第三阶段中，最低能量可以分别降低至170和100eV。
A figure-8 undulator is an insertion device (ID) proposed at SPring-8 to reduce the heat-load problems encountered with ordinary linear undulators. This device is useful when the K value is high in order to obtain low-energy photons as the fundamental of the undulator radiation. It has therefore been adopted as the ID for the soft X-ray photochemistry beamline (BL27SU) at SPring-8 because linearly polarized photons between 100 and 2000 eV are necessary for the experiments on this beamline. The figure-8 undulator for BL27SU is now under construction and, in the first phase of operation, is expected to cover the energy range down to 500 eV. In the second and third phases, the lowest energy may be reduced to 170 and 100 eV, respectively.
