We propose a 50 ks observation of the galaxy group MRC 0116+111. It is an idealtarget for searching for non-thermal, inverse-Compton X-ray emission, becauseits ratio of radio to X-ray luminosity is > 70 times larger than that of anyother known radio mini-halo. Our short snapshot observation with Chandra revealsX-ray morphology extended along the bright radio outflows. The X-ray spectralproperties of the system indicate the presence of an additional non-thermalspectral component. The proposed observation will allow us to disentangle thenon-thermal emission from the thermal component and, in combination with theexisting radio data, place strong constraints on the volume averaged magneticfield.

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.
