Optics

After the restart of the accelerators and the implementation of a specific organization, in particular around the Control Room, the beamlines restarted on Tuesday, May 26.

A first operational nanometric transfer standard

For several years now, the Optics Metrology Laboratory in Optics Group at SOLEIL (LMO) has benefited from LNE (Laboratoire National de metrologie et d'Essais)'s expertise in dimensional metrology by Atomic Force Microscopy (AFM) for the characterisation of the diffractive optics used in SOLEIL's beamlines.

Characterization of the mirrors used on SOLEIL beamlines to focus the radiation to dimensions of a few hundred nanometers requires the development of measuring instruments that are not commercially available. The SOLEIL optics group has thus had to develop, in collaboration with the company EOTECH, a microscope specifically adapted to attain the level of precision required to characterize the optics at SOLEIL.
