ABSTRACT

  This beamline is designed for the transmission mode XAFS measurements using ionization chambers. The various applications of XAFS can be done in the energy range of 3.8 - 113 keV.
  Using the cryostat and furnaces, the sample temperature can be controlled in the range of 4 - 1070 K. A Lytle type detector and 19-element Ge solid-state detector are available for the measurement of the excited spectra. A conversion electron yield detector is available for layered synthetic materials and bulk sample. A θ-2θ stage is used for glancing-angle XAFS measurements. A PILATUS 100K detector is available for depth-resolved XAFS measurements. Time resolved quick XAFS measurements can be performed with time resolution more than 10 sec.
