BL02B2 OUTLINE

Inquiry number

INS-0000000318

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 are large Debye-Scherrer camera with imaging plate as detector and 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
