First results from a dispersive EXAFS beamline developed at INDUS-2 synchrotron source at RRCAT, Indore, India

Commissioning and first results of scanning type EXAFS beamline (BL-09) at INDUS-2 synchrotron source

“…EXAFS beamlines are one of the most significant and extensively used experimental facilities at Synchrotron radiation sources all over the world. At INDUS-2 SRS at RRCAT, Indore, we had earlier developed an energy dispersive type EXAFS beamline at BL-08 port which is operational since 2009 [2]. This beamline covers the photon energy range of 5-20 keV and in this beamline, the entire EXAFS spectrum of the samples can be recorded in a single shot within a time scale of ∼300 msec.…”

X-ray absorption spectroscopy based investigation of local structure in yttria stabilized zirconia nanoparticles generated by laser evaporation method: Effect of pulsed vs CW mode of laser operation

“…A metal film of zirconium and commercial Y 2 O 3 powders were used for calibration of Zr and Y edges respectively. Energy selection was accomplished by using a double-crystal monochromator and X-ray intensity was measured before and after the sample using ionization chambers filled with optimal gas pressure and mixtures [30][31][32][33].…”

Indus-2 Synchrotron Radiation Source: current status and utilization

“…The transmitted intensity representing the EXAFS spectrum is recorded using an x-ray CCD camera with an energy resolution of  1 eV at 10 keV [3]. Many users from universities, national research laboratories and institutes have used the beamline for investigation of a wide variety of problems like determination of structural parameters of metal-organic Cu complexes at the Cu K-edge [4], Eu 3+ assisted structural collapse of GaOOH nanorods [5], study of local structural changes in ZrO 2 due to Nd, La, Gd doping [6] among others.…”
