Galaxy clusters are important tools for probing the cosmic large-scale structureevolution and for performing precision tests of cosmological models. Thelimiting factor for the application of clusters in such cosmological studies iscurrently the uncertainty in the relation between the observed X-ray luminosity(or temperature) and the cluster mass needed for the theoretical modeling. Inview of the large efforts currently undertaken in X-ray cluster surveys andevolutionary studies (also using XMM extensively) it is crucial to pin down thecluster scaling relations at low z in a first step. Therefore we propose acomprehensive, detailed study of a representative cluster sample as an open,Legacy-type project to provide the community with the necessary data.

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.
