RESUMO

The VUV Instrumentation Group of the Laboratório Nacional de Luz Síncrotron is building a beamline of high spectral resolution, based on spherical optical elements. We describe the instrumentation developed to drive the SGM monochromator chamber and an interferometric system to check its angular position. The resolution achieved was in the order of 1 urad. The instrument proved to be linear over its total range, and stable along the time
