Synchrotron Radiation Experiences at APS
    Last two years, I was working at Advanced Photon Source (APS) in Argonne National Laboratory (ANL), USA, using synchrotron X-radiation. I am using X-ray scattering technique in grazing incidence mode with a 2D MAR CCD detector to study the polymer single crystals grown using Dip-Pen-Nanolithography (DPN) technique and organic molecular thin films deposited using spin coating technique. I am also using X-ray standing wave (XSW) imaging technique to determine the relative positions of the organic molecules on the surface lattice.


Synchrotron Radiation Experiences at ESRF
    I worked at European Synchrotron Radiation Facility (ESRF), Grenoble, France, for two months in the beamline ID32 and surface characterization laboratory at ID32. I used their ultrahigh vacuum scanning tunneling microscopy (UHV STM) and molecular beam epitaxy (MBE) system at Surface Characterization Laboratory. I also used synchrotron radiation for x-ray scattering measurements.


Experiences Using Rotating Anode X-ray Source
    I used rotating anode (Mo, Cu) X-ray source for X-ray diffraction (XRD), X-ray reflectivity (XRR) technique to study the MBE grown samples. I was involved in developing an user friendly software for controlling the 4-circle Huber diffractometer and for data collection at Institute of Physics, Bhubaneswar, India.


UHV Experiences: MBE, VT STM and STS
    During my Ph.D. program at Institute of Physics, India, I worked on molecular beam epitaxy (MBE) and variable temperature scanning tunneling microscopy (VT STM). This MBE system is a compact custom designed and contains reflection high energy electron diffraction (RHEED), sputter ion gun and residual gas analyzer (RGA). A UHV VT STM (Omicron) is attached with the MBE for in situ scanning tunneling microscopy and spectroscopy (STS) measurements.


Experiences On Ion Scattering: Ion Irradiation, RBS and RBS/c
    I routinely used 3 MV tandem Pelletron ion accelerators for ion implantation, Rutherford backscattering spectrometry (RBS) and channeling (RBS/c) measurements at Institute of Physics, Bhubaneswar.
