Abell 746 is a unique system hosting a spectacular double radio relic, apossible radio halo, and two radio bright diffuse regions to the east of thecluster. With our proposed XMM-Newton and JVLA observations, along withexisting low frequency radio data, we will (1) understand the origin of complexdiffuse radio sources; (2) probe the underlying particle acceleration mechanism;(3) characterize the properties of the shocks responsible for these sources; (4)determine the merger scenario by comparison with simulations; and (5) studypolarization properties of the relics and the magnetization of the intraclustermedium through Faraday analysis.

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.
