Studies of galaxy clusters are important for both cosmology and the formation ofbaryonic structures. An important relation in cluster science is the f_gas - Mrelation. However, the cluster samples used to constrain this relation are X-rayselected and the current XMM and Chandra archives are also heavily biased toX-ray selected clusters. To address this important bias, we construct a sampleof 11 most massive clusters from the SDSS-C4 cluster catalog. Six of them havebeen observed by XMM or Chandra but they are all X-ray luminous, while the fiveunobserved clusters are X-ray faint. We propose to observe these five clustersto search for X-ray faint, massive cluster, with potentially importantimplications on the cluster mass - proxy relations.

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.
