Large X-ray diffractometer

　The experimental hutch 3 is located in radioisotope (RI) laboratory. X-ray diffraction measurements using coherent X-rays, resonant X-ray diffraction (mainly at K-edge of 3d transition metals, L-edge of lanthanides, and M-edge of actinides (3.5 ∼ 9 keV)) and residual stress distribution measurement, are planned. The system is designed to utilize from low energy to high energy X-rays depending upon the measurement purposes. We have a large X-ray diffractometer on which a bulky apparatus, such as a superconducting magnet, can be mounted. The diffractometer equipped with a polarization analyzer. In addition, there is a phase retarder to control the polarization of incident X-rays, and magnetic circular dichroism experiment can be performed. Sample conditions can be controlled by refrigerators (low temperature), diamond anvil cells (high pressure), and magnets (magnetic field).
