We propose to obtain sensitive XMM-Newton observations of 20 cluster candidateswith significant 148-GHz SZ decrements from the Atacama Cosmology Telescope(ACT) survey that also show correlated RASS X-ray emission. The new XMM-Newtondata will allow us to measure accurate X-ray luminosities and gas temperaturesfrom which we will estimate cluster masses using established scaling relations.This data set forms a mass- and volume-limited sample of massive galaxyclusters.

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.
