We propose to observe five very luminous 3CR quasars, which together with threealready observed, form 4 pairs of sources, each composed by a type 1 and a type2 object, with similar redshift and radio luminosity. These objects are expectedto be the most luminous quasars observed in the X-rays (2-10 keV intrinsicluminosity L>10^{45} erg/s). With these observations we will be able to testwhether the unified model of AGNs still holds at these luminosities in a welldefined, homogeneous and representative sample of objects. We will measure theabsorption properties of these objects, checking whether Compton thick sourcesare common among type 2 quasars.

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.
