We propose to observe a newly discovered galaxy cluster around the radio galaxy3C 210 at z=1.17. We intend to obtain a 20 Ksec ACIS exposure to identify pointsources, which can severely bias measurements of extended emission in high-zclusters, and to study the radio galaxy itself. We also ask to obtain a 100 ksEPIC exposure to measure the properties of the intracluster medium including itsX-ray temperature and morphology. These observations will help to understand theway that galaxy clusters create an ICM as they evolve from the protoclustersrecently discovered at 2<z<4, and to act as a pathfinder for the futureexploitation of high redshift galaxy clusters in understanding dark energy.

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.
