Abstract

The high throughput x-ray Spectroscopy Mission XMM is a 'Cornerstone' project of the ESA Horizon 2000 Science Program. The optical heart of this satellite consists in 3 Mirror Assemblies (MA). Each MA includes a Mirror Module (MM) containing 58 x-ray optical quality Mirror Shells (MS) and an x-ray (XRB) which reduces straylight. Two of the three MAs are equipped with a Reflection Grating Assembly (RGA) for spectral analysis. Tests are performed in the CSL FOCALX facility. The goal of the presented tests is to evaluate the x-ray effective area of a MM. These test are accomplished in a vertical configuration. An x-ray pencil beam is used for x-ray reflectivity measurements at Al, Au, Cu and Mo lines between 1.5 and 13 keV. A partial illumination collimated x-ray beam with a C continuous spectrum allows to measure the effective area of the MM over a 1.5-9 keV range. This paper gives a short description of the tested specimens, and presents the test configuration in CSL Focal X facility. The paper focuses on a compete and original way to work out experimentally effective areas of an x-ray telescope. Analysis of the achieved results is carried out.
