Abstract
A high resolution vacuum ultraviolet beamline has been developed and installed at the 450 MeV synchrotron source Indus-1 operating at the Raja Ramanna Centre for Advance Technology, Indore, India. This beamline is useful for photoabsorption studies of atoms and molecules in the VUV region of 1050–3000 Å. The beamline consists of three major components: a pre-focusing optical system, a gas phase absorption setup and a 6.65 m vacuum ultraviolet spectrometer in off-plane Eagle mount. The performance of the beamline has been evaluated by recording VUV absorption spectra of xenon, oxygen and sulphur dioxide using synchrotron radiation from Indus-1. The resolution achieved is 0.1 Å with a 1200 ln/mm grating. Spectra obtained agree well with the ones published earlier. Details of the design, development and performance testing of the beamline are discussed.
