Abstract We propose to observe three well-studied cluster gravitational lenses,which are amongst the most X-ray luminous and massive systems known atintermediate redshifts. The observations will permit accuratedeterminations of the X-ray gas mass, total mass, baryon and metallicitydistributions in the clusters. The data will reveal the impact of coolingflows on X-ray mass measurements and elucidate the origins of thediscrepancies between X-ray and strong lensing masses for clusters withoutcooling flows. The data will also provide a crucial step in establishingthe mass/temperature relation for luminous 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.
