BL22XU OUTLINE

Inquiry number

INS-0000000327

ABSTRACT

 BL22XU was constructed as a hard x-ray undulator beamline, extending to the RI building through the experimental hall of the storage ring building, and starting operation in May 2002. JAEA promotes fundamental and applied research on the actinides science and also contributes to restore the environment of Fukushima, with complimentary use of another beamline BL23SU, which also led to the RI building for supplying soft x-rays. This beamline has experimental stations in the storage ring building and the RI building. The RI building is dedicated to treat radio isotopes including transuranic elements as sealed materials. For now, users can conduct their experiments using high pressure, coherent x-ray, etc., as this beamline is equipped with a few experimental apparatus within QST’s jurisdiction.

SOURCE AND OPTICS

 The light source is an in-vacuum undulator with a periodic length of 38 mm, whereby x-rays of 5 - 70 keV are available as first harmonic up to fifth harmonic radiations.
 There are two double crystal monochromators installed in the optical hatch. One is a calculated-coupled monochromator used at a fixed energy between 35 keV and 70 keV. A pair of Si (111) crystals can disperse high intensity x-rays. The other is a cam type monochromator for quick scan and it covers just from 5 keV to 70 keV as the cam type monochromator has Si (111) and Si (311) crystals, which is possible to switch crystals under liquid nitrogen cooling temperature and high vacuum.
 As a focusing device, a set of beryllium refraction lenses is installed in the optics hutch. In addition, a first mirror and three second mirrors are installed in the experimental hutch 2 to focus incident X-rays and cut higher harmonics parts. The first mirror M1 is a mechanically-bent plane mirror for vertical focusing. The second mirrors M2, M3, and M4 are cylindrical mirrors for horizontal focusing, and are used in energy ranges 5 ∼ 7 keV, 7∼16 keV and 16∼30 keV, respectively.
