ABSTRACT

  The BL02B2 is a beamline for powder diffraction using high-energy synchrotron radiation, and is designed for charge density study by powder specimens in the area of materials science. There is powder diffractometer with multi modular system constructed by six MYTHEN detector in experimental hutch. The beamline optics covers x-ray energy range from 12 keV to 37 keV. This beamline makes it possible to collect powder diffraction data with a high-counting statistics and high-angular resolution, which must contribute the improvement of the accuracy of structure analysis of crystalline materials.

AREA OF RESEARCH

• Charge density studies closely related to properties of functional materials
• Structural aspects of phase transition
• Ab initio structure determination using powder diffraction data
• Structural refinements by Rietveld method
• In-situ powder diffraction experiment under gas and vapor adsorption/desorption
