Abstract Chandra and XMM are extending the minimum luminosity to which X-ray clusters canbe detected and analyzed at intermediate redshifts, probing massescharacteristic of poor clusters. Strong lensing systems with image separationsin the range 6-16 are starting to be detected thus opening also with thistechnique a new window of exploration in this crucial mass range. Anunprecedented opportunity of X-ray-lensing comparison is therefore opening in anunexplored lower mass regime compared to the one of massive clusters. Therefore,we propose to continue a snapshot survey of 5 promising strong lensing poorclusters (one object has been awarded in AO9) to secure their X-ray fluxes. Deepfollow-up exposures with Chandra will then be proposed for detailed analysis of the mass profile.

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.
