Abstract The clusters A548b and A1664 are peculiar in the radio domain because of thepresence of radio relics. These are very extended diffuse radio sources, locatedin cluster peripheral regions, and associated with the intracluster medium.According to theoretical models, the radio relics are energized by clustermerger shocks. We wish to investigate the cluster X-ray properties, the statusof the intracluster medium, the presence of shocks, filaments or cold fronts, inorder to analyze the energy transfer between the thermal gas and the radioemitting particles. The study of the connection between X-ray and radio emissionwill be crucial to understand the formation of relics, and more generally of thenon-thermal components 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.
