| Abstract | We propose to take advantage of the low interstellar absorption in the W0.2-2.1window (l=0.2,b=-2.1, NH ~ 4e21 cm-2 to carry out a deep survey of the centralparts of the Galaxy. We shall detect faint X-ray bulge sources with Lx above3e31 erg/s (0.5-2 keV) and shall probe the galactic disk population over thefirst ~ 4 kpc. This window which is the closest known to the galactic centeroffers unique prospects for optical identification and follow-up studies atlarge distances. Among expected bulge sources are cataclysmic variables, X-raytransients in quisecence and progenitors or descendants of the bright low massX-ray binaries. |

| 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. |
