The X-ray Photo-Electron Spectroscopy (PES) beamline is devoted to the high-resolution photoelectron spectroscopy of solids in the hard X-ray region The beamline is installed at 1.5 T bending magnet source of Indus-2. The most of the components of the beamline are indigenously designed and developed and the beamline covers an energy range from 2 keV to 15 keV. It facilitates the powerful technique of XPS to probe the elemental composition, chemical states and electronic states of elements in near surface region of both thin films and bulk materials. In this technique, a material is bombarded by high energy X-rays from synchrotron and an energy spectrum of emitted photo-electrons is analysed. The spectrum is used to calculate binding energy of electrons in the material which in turn provides information of elements present on the surface and their bonding with other elements. Conventional lab based PES provides information of the materials up to a depth of about 1 nm from the surface due to small mean free path of emitted electrons. The high energy X-ray would provide information at larger depths ( ̴10 nm) due to increase in the mean free path with electron energy.
