We propose to extend our systematic X-ray studies of the most-distant knownquasars with XMM-Newton spectroscopy of five typical radio-loud quasars (RLQs)at z = 3.98-4.97. Our targets are more representative of the overall RLQpopulation than the small number of highly radio-loud blazars studied at z virgul 4,and we have detected all targets in exploratory Chandra observations. We willsearch for X-ray absorption in the quasars. environments to determine if it iscommon among typical RLQs at the highest redshifts. We will also measure X-raycontinuum shapes and search for variability and clustered AGN.

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.
