Abstract	We propose to measure the X-ray spectra of 5 quasars with z>4. We have carriedout a survey of 14 optically bright, radio-quiet z>4 quasars using short ChandraACIS-S exposures. From the measured fluxes, we can estimate exposure timesrequired for spectroscopy. To date, only four z>4 quasars have X-rayspectroscopy, and all 4 are radio-loud blazars. Our sample includes one z=5quasar, and we ask for a deep exposure which may detect its flux to 60 keV inthe rest frame. We can test whether the high energy turnover seen in localSeyferts is present in this z=5 quasar. The only other z>5 quasar with ameasured X-ray flux is too faint to obtain spectroscopy in a reasonable exposuretime.

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.
