We propose to continue our approved XMM program to obtain detailed X-rayspectral and structural data for distant, optically-selected clusters. Theseobservations will, for the first time ever, allow is to place accurateconstraints on the temperature, metallicity, and gas mass fraction in theintracluster medium of rich, optically-selected clusters at high redshift. Thetarget clusters are the most well-studied systems at z greater than 0.7 in theoptical and infrared; thus, the addition of XMM data will enable us to probe therelationship between the X-ray and optical properties and their implications forgalaxy and cluster evolution. Our program provides an essential comparisonsample to those well-studied, X-ray-selected clusters at similar redshifts.

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.
