Recent discoveries of high-redshift quasars have provided new opportunities toinvestigate fundamental properties of the early Universe. X-ray observations ofthis quasar population are especially important for studies of black holeformation and the initial stages of feedback. We propose observations of twohigh-z radio-loud quasars with X-ray properties that represent the extremes ofcomparable sources to perform the following\: (1) establish the formation of aCompton thick absorber at high redshift, (2) investigate the accretion diskstructure via Fe K intensity and broadening. These results will provide aninvaluable perspective on X-ray emission from exotic systems and establish thediversity in X-ray emission from young radio sources at the highest redshifts.

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.
