A synchrotron X-ray diffractometer incorporating a pulsed field magnet for high fields up to 40 T has been developed and a detailed description of this instrument is reported. The pulsed field magnet is composed of two coaxial coils with a gap of 3 mm at the mid-plane for passage of the X-rays. The pixel detector PILATUS 100K is used to store the diffracted X-rays. As a test of this instrument, X-ray diffraction by a powder sample of the antiferromagnet CoO is measured below the Néel temperature. A field-dependent lattice distortion of CoO due to magnetostriction is observed up to 38 T.
已开发出一种结合了用于产生高达40 T强磁场的脉冲场磁体的同步加速器X射线衍射仪，并报告了该仪器的详细描述。脉冲场磁体由两个同轴线圈组成，在中平面处有3 mm的间隙以供X射线通过。像素探测器PILATUS 100K用于存储衍射的X射线。作为对该仪器的测试，在奈尔温度以下测量了反铁磁体CoO粉末样品的X射线衍射。观察到由于磁致伸缩导致的CoO晶格畸变与磁场有关，最高可达38 T。
