Abstract

 

 

 The beamline called Crystal Structure Analysis is assigned to four subgroups, that is, Structural Phase transition, Highly Precise Molecular Crystallography, Diffuse Scattering and High-Resolution Powder groups. These groups handle materials to study structural aspects by fixed energy X-ray beam commonly. However, there are divergences in techniques such as crystal size, variation of atmospheres of samples, requirements of resolution function for the diffraction experiments and so on. The structural phase transition group became the group leader of this project to organize and converge the requirement for the system settled on the beamline.

 The main concept of this beamline is to construct the machine as the general purpose for the diffraction experiments to include all of necessary demands of these four groups. They proposed the high flux and high energy beamline by using the radiation generated from a bending magnet in order.

  1. to observe various weak diffraction such as diffuse scattering or superlattice diffraction utilizing the high flux radiation,
  2. to collect a lot of diffraction data for precise structural analysis by utilizing high energy radiation and expanding the observable reciprocal lattice volume.

 The experimental station is designing by the collaboration of four groups. The central part of the station is the sevenaxes diffractometer. It is very similar with the conventional six-axes diffractometer commonly used at many beamlines of synchrotron radiation facilities, and one extra two-theta axis is added. The purpose of the extra axis is to be specialized for the conventional structure analysis to give the high speed motor function. Off-center type chi-cradle is planned to put a cryostat, a furnace, a vacuum chamber and a spindle for powder sample on the phi-circle. Many other optional tools is be planning, for instance, a high precision solar slit, Imaging plate system for photographic method.

Abstract

 The experimental hutches for the high temperature research will be built at the BL04B1 bending magnet beamline. This beamline has no monochrometer and white x-rays will be supplied for the experiment. Two scientific subgroups, high pressure mineral physics group and high temperature group, are planning to carry out their experiment in the two experimental stations tandemly built on this beamline.

High Pressure Mineral Physics

Research Subjects

  • Structure of the Earth’s Mantle and Core
  • Magma and Molten Metal in the Earth’s Interior
  • In situ Observation of Diamond Synthesis

 

Facilities

  • 1500 ton Large Volume Press with 6-8 Multi-Anvil Type High Pressure System 40 GPa, 2500 C
  • Vertical and Horizontal Goniometer

 

 The aim of the high pressure mineral physics group is to reveal the origin, evolution and present state of the internal structure of the Earth and other planets. For this purpose, various properties of planetary materials, such as iron, silicates, hydrogen and helium, will be investigated under high pressures and high temperatures. In particular, in situ x-ray diffraction experiment under high pressure and high temperature will be mainly carried out using the polychromatic x-rays from a bending magnet. The extreme pressure and temperature conditions corresponding to those of planetary interiors can be obtained with a multi-anvil type high pressure apparatus, which will be installed on this beamline. This high pressure apparatus has a 1500 ton ram-force uniaxial press with a cubic anvil type guide block, and is operated in the two-stage mode (so called 6-8 system) to reach the desired P-T conditions. This system has a capability of generating pressures up to 40 GPa and a temperature of 3000 K using a solid pressure medium. For the x-ray experiments, two single-axis goniometers (vertical and horizontal directions) are equipped by the high pressure press. The Ge solid state detector is used for the energy dispersive x-ray diffraction experiments.

 

 

High Temperature

Research Subjects

  • Structural Studies for Expanded Fluid Metals and Semiconductors
  • Partial Structures in Multi-Component System
    • Anomalous X-ray Scattering
    • XAFS
  • Structural Studies at Extremely High Temperatures

 

Facilities

  • High Pressure Gas Vessel
    Helium 2000 kg/cm2, 1650 C
  • Horizontal Goniometer
  • Protection Wall

 

 The high temperature group is planning to investigate the structural properties of disordered materials under high temperatures. One of the biggest topics is the structural studies of expanded fluid metals and semiconductors. When liquid metals are heated and pressure is applied to prevent boiling, significant density decreases can be achieved. When temperature is elevated at low pressure, a first-order phase transition from liquid to gas occurs accompanied with increasing pressure, and disappears at the critical point. At the pressure higher than this critical pressure, the volume of expanded fluid can be changed continuously in a wide range by heating. The structure of these expanded fluids, such as Hg and Se, will be investigated in a wide density range by the x-ray diffraction measurements and the small-angle x-ray scattering. In the experimental station, a high pressure gas vessel and an energy dispersive x-ray diffractometer will be installed. This high pressure vessel permits x-ray diffraction measurements at high temperature and pressure up to 1650 C and 2000 kg/cm2. Since helium high pressure gas is used as pressure medium, all these facilities will be placed in small rooms surrounded by the protection wall built inside the hutch.
