We propose to take advantage of the low interstellar absorption in the W0.2-2.1window (l=0.2, b=-2.1, NH virgul 4e21 cm-2) to carry out a deep survey of the centralparts of the Galaxy. We will detect faint X-ray bulge sources with Lx above 3e31erg/s (0.5-2 keV) and will probe the galactic disk population over the first virgul 4kpc. This window which is the closest known to the galactic center offers uniqueprospects for follow-up studies at large distances. Among expected bulge sourcesare cataclysmic variables, X-ray transients in quiescence and progenitors ofbright low mass X-ray binaries. Our AO3 XMM-Newton observations allowed us toonly reach the brightest part of these X-ray sources. First results of adedicated follow-up with the VLT/VIMOS confirm the nature of the expected population.

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.
