A key ingredient of structure evolution at late times is the accretion energythat is redistributed into the external medium through radio sources, via poorlyunderstood energy-exchange mechanisms. Many sources in group environmentsdisplay prominent belt-like X-ray structures that are associated with thecentral narrowing of radio sources between their X-ray-filled lobes. The beltsare not like cluster cavity features, and could either be a driven outflow ofcooler gas from the centre, and a potential barrier to feedback, or displacedgas associated with fuelling the AGN, potentially causing runaway feedback. Wepropose to test which is the case in 3C 386, our best example of a nearbydouble-lobed radio source with a prominent X-ray belt in a poor environment.

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.
