Both X-rays and gravitational lensing are highly recognized paths to carry outcosmological studies, with several space missions being prepared: eROSITA,EUCLIDE, JDEM. Galaxy clusters which are going to be found in all those surveyswill provide a quantum leap in our understanding of the Cosmology. We proposehere a unique path-finder survey optimized for a joint X-ray and gravitationallensing cluster detection in the redshift range of 0.1-1. This proposal is ajoint program on calibrating and extending the 400 square degree survey topursue the measurement of dark energy to 3% accuracy achieved in a combinationwith WMAP, BAO and SN experiments.

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.
