The QSOs RBS 1423 (z=2.26) and RBS 825 (z=1.57) are the most X-ray luminousradio quiet AGN in the ROSAT bright source catalogue. No radio quiet QSOs ofcomparable X-ray flux and luminosity have so far been observed by XMM-Newton orChandra. We propose to obtain high quality EPIC spectra for both QSOs in orderto investigate the reprocessing of the primary X-ray emission in high luminosityAGN. Due to the redshift of the objects important spectral features as the 6.4keV iron fluorescence line, the iron 7.11 keV absorption edge and the Comptonreflection hump are redshifted to favourable energies.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
