We propose to obtain ACIS and EPIC observations of an X-ray selected cluster ofgalaxies from the ROSAT Distant Cluster Survey (RDCS). From the combined Chandraand Newton data we will determine the X-ray temperature (Tx) of the intraclustergas, thus completing our measurement of Tx for all 10 z>0.8 clusters found inthe RDCS. We will use these combined observations to achieve the followingscience goals: 1) determine the temperature function for a complete sample of 10clusters in the RDCS with z>0.8, and 2) calibrate the cluster total mass--Txrelation at these high redshifs.

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.
