The cluster RXCJ0548-2154 (A3365) is a merging system with a pronouncedperipheralradio relic. Similar to the prototype system A3667 the relic is almostaligned with the merger axis and the cluster shows a simple head-on mergergeometry. This clear morphology and the fact that the cluster has a low redshiftof z=0.0928 makes it a very attractive object for the study of the mergingprocess in connection with cosmic ray acceleration. To detect a shock near therelic position, to get a postshock temperature, and to unravel the mergerdynamics we propose a deeper XMM-Newton observation of 120 ks.

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.
