We propose to obtain XMM-Newton observations for a complete flux-limited sampleof 7 of the most mid infra-red luminous quasars (log(L6um) > 47.5) at the mainepoch of galaxy and black-hole growth at z 2 3. The main objective is to studythe X-ray properties of a new population of hyperluminous, heavily reddenedquasars with typical extinctions of 0.5 < E(B V ) < 2.0 and which are thereforenot detectable in wide-field optical surveys. These broad-line Type 1 reddenedquasars have the expected properties - high Eddington ratios and moderatecolumn-densities - characteristic of the radiative feedback phase. We willconstrain the hard X-ray luminosity and neutral hydrogen column density andcompare them to optically selected, essentially unobscured 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.
