Vacuum UV Spectroscopy

Vacuum UV Optics

With the third generation storage ring the synchrotron source characteristics were dramatically improved. In particular the source brilliance is 4 or 5 orders of magnitude higher than that obtained with the second generation storage ring and the emittance is 3 orders of magnitude lower. This spectacular source parameter evolution generates needs of new optical substrates with better performance under high flux (lower deformation) and new optical configuration to increase spatial and energy resolution.

To answer to these needs HORIBA Jobin Yvon concentrated on three main activities:

  • Conception of new gratings with better efficiency and lower stray light.
  • Technical amelioration and control improvement to reduce grating and mirror slope error and roughness.
  • Development and construction of new components that can be easily adapted in new generation beamline.

To achieve this goal HORIBA Jobin Yvon started a collaboration with LURE (Orsay - France). This permits us to:

  • Develop new software for ray tracing and beamline optimisation.
  • Realise software for grating efficiency calculation and parameter optimisation.
  • Perform in-situ tests on VUV products.
