Abstract We propose to complete our X-ray follow-up program aimed at observing the ACTCosmological Sample of Clusters, which is a well-defined sample of 22 massivegalaxy clusters detected by the Atacama Cosmology Telescope using theSunyaev-Zel.dovich effect (SZE). There remain five newly-discovered SZE clustersin this sample without any X-ray data. The proposed XMM-Newton EPIC observationswill provide accurate gas masses and temperatures to be used for a precisioncalibration of the SZE signal versus mass scaling law out to redshifts of 1.This effort is an essential part of our intensive multi-wavelength campaign toobtain mass measurements for the ACT Cosmological Sample of Clusters.

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.
