Abstract:
The photoabsorption spectroscopic studies (PASS) beamline (PASS-BL07), installed at a bending magnet 450 MeV, 100 mA Indus-1 synchrotron source (India), is capable of performing photoabsorption studies in the vacuum ultraviolet to soft x-ray range of thin films and solid samples. The beamline covers an energy range of 55 eV-840 eV by an in-house developed SX-700 type plane grating monochromator. This energy range will cover the absorption spectra of low Z-elements like C, N, and O as well as the L and M threshold of 3d elements such as Ti, V, S, etc. The beamline will be significantly used for studying organic semiconductors, graphene, etc. In this article, the design details of the beamline and some of the recent scientific results have been presented.
