At the Institute of Nuclear Physics, a nine-pole hybrid wiggler is developed and successfully installed on the VEPP-4 accelerator complex. The nine poles of the wiggler are electromagnets with iron cores. To achieve the largest field, permanent magnets with a residual induction of 1.2 T are installed between the wiggler poles. Such a combination of electromagnets and permanent magnets made it possible to achieve a maximum magnetic induction of 1.9 T, with an interpolar gap of 30 mm. Currently, at the Siberian Center of Synchrotron and Terahertz Radiation, several research methods using the “hard” X-ray range (50–250 keV) based on radiation from a nine-pole wiggler are being certified. For example, using this radiation, the X‑ray imaging of fast processes, X-ray computed tomography, X-ray fluorescence analysis, and X-ray diffraction studies are carried out. A brief review of these studies is presented. © 2020, Pleiades Publishing, Ltd.
