| Abstract | We propose a moderately deep (120ks each for two positions) XMM observation ofthe existing Chandra Large Area Synoptic X-ray Survey of the LockmanHole-Northwest field. This field represent the largest fully analyzed largesolid angle, sensitive Chandra survey. In the uniform 36x36 Chandra solidangle we have obtained optical spectra and redshifts of over 250 of the 525sources as well as very deep (27 mag) optical multi-band images. Of thesesources 127 of them are brighter than 1e-14 c.g.s where good quality XMM X-rayspectra are possible in moderate exposure times. The unique combination of XMMspectra and timing data, Chandra positions, and very deep optical,near-infrared, far-infrared, and submillimeter observations will enable the |

| 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. |
