We propose a 10-40ks/field XMM survey over 50 deg2, designed to constrain thedark energy equation of state using the 600 - 1,400 clusters of galaxies that wewill detect. The constraints that we will achieve on w_0 and w_a, of 0.7 and 2.4(10ks coverage) and 0.4 and 1.2 (40ks coverage) are at the level of the ultimateStage-IV DETF accuracy estimates achievable by cluster studies. This survey willalso have lasting legacy value for cluster scaling laws and studies of AGN andXRB.

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.
