The most X-ray luminous and massive galaxy clusters are the most interestingobjects for astrophysical and cosmological studies. Completing our REFELX IIcluster survey, we added 10 of the most luminous clusters in the redshift rangez=0.3-0.5 at dec<-40. This category of clusters has already received tremendousattention as witnessed by a series of studies on cluster structure, lensingproperties, SZ observations, galaxy population and dynamics. They are also themost important cosmological probes at the intermediate redshift to tracelarge-scale structure evolution, and to constrain cosmological parameters.Therefore we propose XMM observations of the 7 remaining luminous clusters to asufficient depth to precisely assess their physical properties.

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.
