GT- A deep XMM pointing will be obtained for the AXAF Ultra Deep Field southerncounterpart of the Lockman Hole.The XMM observations will provide spectroscopicinformation of faintsources complementary to the spatial information given byAXAF data. In about 400 ksec, detailed spectral analysis will be achievable forsources with 10**4 counts or a flux of 1.5* and 3*10(-14) erg/cm**2 sec in the0.2-2kev and 2-10keV bands respectively, well above source confusion. From ROSATDeep Surveys, one expects about 15 extragalactic sources for which detailed spectral analysis can be carried spectroscopic information. Combining the AXAFand XMM data will give firm limits out and up to about 120 sources with coarseon XMM source confusion and help to determine the fluctuations of the X-ray BG.

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.
