X-ray diffraction studies in pulsed high magnetic fields

Abstract

X-ray diffraction studies have been performed up to 38 T in conjunction with synchrotron x-ray beams and a split-pair pulse magnet at the beamline BL19LXU of SPring-8. The magnet consists of coaxial two-coils which are made by winding CuAg wire up to 18 layers. The magnet has four windows with wide aperture angles and the height of 3 mm for passage of the x-ray beam. A pixel array detector was used to measure the diffraction patterns during an exposure of 5 millisecond around the peak field. The details of the instrumentations are presented.
