Abstract Measurements of galaxy cluster temperature evolution provide tight constraintson cosmological parameters. Clusters have a wide range of temperatures, so characterizing the evolution requires a determination of the temperature function (TF) over a range of redshifts. There are virgul6 nearly independent low z TF measurements, but only 1 at high redshift. We propose to obtain the second.We will compare our independent determination with the existing high z TF tocheck for biases and systematics. Our simulations indicate that none will befound. If so, both samples will provide constraints on cosmological parametersthat are highly complementary to those from supernovae and the microwave background.

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.
