Abstract	We propose a joint XMM-NuSTAR observation of the cluster Abell 523. We recentlyfound in this cluster a radio halo that is striking because it is in a lowluminosity X-ray cluster, outside of the well established radio power - X-rayluminosity relation for radio halo clusters. This challenges the currentscenario for radio halo formation. The joint XMM-NuSTAR observation will afforda detailed mapping of the surface brightness and temperature distribution of thethermal gas and will allow a detailed investigation of the Inverse Compton (IC)emission in one of the best targets to perform this search. In the case of adetection it will provide a measurement of the spatial distribution of the ICemission and a measurement of the magnetic field.

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.
