GT-We propose observations of two of the most X-ray luminous clusters,A2218 (z=0.178) and RXJ0658-55 (z=0.32), found to be very massive. Both clustersact as gravitational lenses and feature a strong Sunyaev-Zeldovich effect. A2218 provided the first clear SZ detection and RCJ0658-55 is one of two clusters for which an SZ increment is detected. Both are merging systems making the analysis of previous data difficult. XMM providing information on the temperature distribution is essential for a correct modeling. The two targets are ideal for a combined study ofthe X-ray structure, lensing mass distribution, and SZ effect in moderate redshift clusters without cooling flow.

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.
