We propose to use XMM to confirm the identification of a distant clustercandidate that was selected from the ACBAR Sunyaev-Zel.dovich (SZ) Blind ClusterSurvey. This candidate shows a strong SZ decrement, at a level consistent with a1.1e15 solar mass cluster, in a deep ACBAR observation. Deep r and i bandimaging has uncovered an obvious over density of faint galaxies that was notvisible on the UKST survey plates. If confirmed in the X-ray band, this will bethe first cluster to have been discovered via its SZ signal alone (rather thanvia its optical, radio or X-ray signatures). XMM will be the first satellite tomake this important discovery.

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.
