Abstract

The high throughput x-ray spectroscopy mission XMM is the second 'Cornerstone' project in the ESA long term Programme for Space Science. This observatory has at its heart three heavily nested Wolter I grazing incidence x-ray telescope. The telescopes are equipped with non-dispersive spectroscopic imaging instruments and medium resolution dispersive spectroscopic instruments. Because of the sensitivity of the XMM instruments x-ray detectors in the visible wavelength range, a high suppression of the visible radiation emitted from out-of-field sources must be ensured. The straylight reduction capability is quantified by the PST. The experimental verification of the PST on the XMM flight model mirror modules for off-axis angles between 1 degree and 85 degrees is presented in this paper. For the first time a straylight test of a compete telescope was performed in air measuring the telescope PST over a range of 9 orders of magnitude.
