We propose to carry out a deep survey in hard X-rays in the Lockman Hole by complementing the 150 ksec of the PV phase observations with another 200 ksec.The scientific goals include: 1. testing the AGN origin of the X-ray background by detecting hard X-rays in all soft X-ray sources, 2. test specific unified scheme models for the XRB, 3. detection of virgul30 Compton-thick AGN in hard X-rays,4. detection of the hard X-ray sources missing in soft X-ray surveys, 5. direct determination of hard X-ray source counts down to a 2-10 keV 2E-15 erg/cm2/s and6. determination, via fluctuation analyses, of 2-10 keV source counts to muchfainter fluxes.

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.
