We propose to measure the mass profiles of a complete sample of massive galaxyclusters at 0.9< z< 1.15, with a precision similar to that currently obtainedfor local objects. We will assess the evolution of the dark matter concentrationat cluster scales, a critical test of theoretical scenario of structureformation. This data set will also constrain the evolution of fundamentalmass-proxy relations and the evolution of the gas entropy and pressure profilesin the high mass regime, a test of gravitational gas heating

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.
