An in-vacuum minipole (short-period) insertion device has been developed in a collaboration between SPring-8 and the National Synchrotron Light Source (NSLS). The magnetic arrays were constructed by SPring-8 and were installed in a chamber with mechanical parts in the X-ray ring (E = 2.584 GeV) at the NSLS in May 1997. The device is made of permanent magnets with 30.5 periods and a period length of 11 mm. It is designed to produce fundamental radiation at 4.6 keV, and, with a modest value of deflection parameter (K = 0.7 at 3.3 mm gap), enables higher harmonics to be used for a variety of experiments.
一个真空型小极（短周期）插入装置由日本的SPring-8和美国国家同步辐射光源（NSLS）合作开发。磁阵列由SPring-8构建，并于1997年5月安装在NSLS的X射线环（能量E = 2.584 GeV）中一个带有机械部件的腔室内。该装置由具有30.5个周期且周期长度为11毫米的永磁体制成。它被设计用于产生4.6 keV的基波辐射，并且，在适度的偏转参数值（在3.3毫米间隙时K = 0.7）下，能使更高次谐波用于各种实验。
