Angle Dispersive X-Ray Diffraction Beamline (BL-12)

Introduction

X-ray diffraction (XRD) is a powerful technique for studying the structure of materials - both crystalline as well as amorphous. The combination of high brightness and fine vertical collimation of synchrotron radiation with the added advantage of broad range of wavelength tunability as compared to conventional laboratory x-ray sources makes it an ideal source for XRD characterization of materials.

An angle dispersive X-ray diffraction (ADXRD) beamline has been setup and installed on BL-12 bending magnet port of the Indus-2 synchrotron. The electron source size at this port is approximately 0.5 mm (H) X 0.5 mm (V). The beam acceptance of the beamline is 2 mrad(H) x 0.15 mrad(V). The first optical element is a platinum coated pre-mirror (M1) which is plane and bendable and is used for vertical focusing/collimation of the x-ray beam. Double Crystal Monochromator (DCM) with Si(111) crystals is the second optical element of the beamline and is used for monochromatization of photon beam. Second crystal of the DCM is also used for the sagittal focusing of the beam. For high energy resolution Si(311) crystal pair is also available which requires approximately 3 days for being replaced and aligned. The third optical element is a platinum coated bendable post mirror (M2) used for vertical focusing/collimation of the beam (Post mirror has been removed temporarily).

Experimental Stations Available

There are two experimental stations in tandem. The adaptive focusing optics allows us to focus the photon beam on one or the other experimental station. The first experimental station consists of a six circle diffractometer (Huber-5020) with NaI scintillation detector. The four circles consist of θ, 2θ,φ and X rotations.φ and X rotations are used to adjust single crystal samples. The second experimental station consists of an area detector (Image Plate Mar-345) for fast recording of XRD data on powder sample.

Research Highlights
  1. X-ray diffraction studies of Gd1-xCaxBaCo2O5.5 system (0 <= x <= 0.30)
    		2.


  2. Determination of concentration of Eu valence states in EuCu2Ge2 using XANES
  3. Ordering of a'-Fe,Co nanocrystalline phase in soft magnetic FeCoNbB alloy

  4. XRD study of correlation of the magnetic properties of Cu free FINEMET alloys with air annealing at various temperatures.

  5. Investigation of charge states and multiferroicity in Fe doped h-YMnO3


    Low level Fe-substitutions on Mn site in YMnO3 multiferroic clearly contrast the roles of magnetic versus non-magnetic B-site dopants. The doped magnetic Fe ions weaken the Mn-Mn interaction. Doping driven enhanced charge disorder (Mn+3 / Mn+4) quenches the spin frusration (f); this affects the biferroicity minutely, but alters their coupled magneto-electric features hugely.
