La spectrometrie par transformation de Fourier est une technique maintenant bien maitrisee, qui permet d'obtenir des spectres a la fois exacts et a tres haute resolution, de l'infra-rouge lointain a l'ultra-violet, jusque vers 140-120 nm. En dessous,

A Fourier transform spectrometer dedicated to Vacuum Ultra-Violet [180-40nm] photoabsorption has been developed. The first experimental results, presented here, show unprecedented resolving power (above 700000). The instrument is an endstation on the

We describe a Fourier transform (FT) spectrometer designed to operate down to 60 nm (20 eV) on a synchrotron radiation beamline for high resolution absorption spectrometry. As far as we know, such an instrument is not available below 140 nm mainly be
