The clusters A548b and A1664 are peculiar in the radio domain because of thepresence of radio relics. According to theoretical models, the radio relics areenergized by cluster merger shocks. With this proposal we wish to investigatethe cluster X-ray properties, the status of the intracluster medium, thepresence of shocks, filaments or cold fronts, in order to analyze the energytransfer between the thermal gas and the radio emitting particles. The study ofthe connection between the X-ray and radio emission will be crucial tounderstand the formation of relics, and more generally of the non-thermalcomponents in clusters, and their relation to the cluster dynamics.

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.
