We propose the completion of the study of a statistically complete sample of 13massive, distant REFLEX cluster allocated in AO1 for which 5 out of 12 clusterobserved so far yielded observational data heavily contaminated by proton flaresand unusable for the major goals of the proposed project. The main aim of theproject is the construction of the X-ray cluster temperature and mass functionfor the test of cosmological models. We have also started an in depth opticalstudy of these clusters at ESO to determine the galaxy dynamics, obtain a censusof the star formation rate in the galaxy population, and to monitor itssupernova rate. To complete this project we need good observational data of allthe clusters and therefore request the reobservation of those 5 objects.

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.
