We propose a deep observation of the z=0.43, T=5 keV galaxy cluster XLSSC 006.Its Sunyaev- Zel.dovich (SZ) signature was detected with high signal to noise at150 GHz by the APEX-SZ instrument. This makes XLSSC 006 the coolest cluster everdetected in SZ. Combining our well resolved SZ map with a high sensitivity XMMobservation will permit to derive for the first time the gas temperature profilefrom a deprojection of the SZ and X-ray surface brightness out to at least0.8xr500. This will further enable us to estimate the average temperature of theRzCS 059, a red sequence selected cluster at z=0.9 and add two interestingpoints in the scaling relations for low mass systems. Possible other X-raydetections could also be correlated to less significant SZ decrements visible in the field.

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.
