Description
Summary: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.
