Paper Abstract

The x-ray multi-mirror mission is the second of the four cornerstone projects of the ESA long term Program for Space Science. The payload comprises three co-aligned high throughput imaging telescopes called mirror modules. The 'Centre Spatial de Liege' (CSL) is in charge of optical and environmental qualification test of each of these MMs. To perform optical tests, a vertical test facility (FOCAL X) has been developed by CSL. An EUV channel providing an 800 mm diameter collimated beam is used. A trade-off leading to the selection of an electron cyclotron resonance EUV source is presented. Impact of the coating on the microroughness of the EUV optics is assessed and its homogeneity across the optical surfaces is measured. Another feature of the facility is an x- ray channel providing a 50 (DOT) 8 mm2 collimated beam. It has been characterized for x-ray effective area measurement. It is the first time that an off-axis parabolic mirror is used for this purpose.
