We propose XMM-Newton EPIC observations of a sample of four high redshift galaxyclusters with 0.87 < z < 1.20 discovered by the 42 square degree SpitzerAdaptation of the Red Sequence Survey (SpARCS). This survey is currently thelargest optical/IR survey for high redshift clusters, and includes significantmulti-wavelength follow-up. Extensive Gemini spectroscopic observations haveconfirmed that all of our targets are rich, massive clusters with velocitydispersions ranging from 550-800 km/sec. Our XMM observations are designed todetect the extended intra-cluster medium in the cluster cores, provide firstestimates of cluster X-ray luminosities, and broadly investigate the core gasdensities of our targets.

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.
