SN 1006 was shown by ASCA to be of a dual nature, with non-thermal emissioncoming from the bright limbs superposed on fainter thermal emission. This is thebest example we have of shock acceleration of cosmic-ray electrons to energiesapproaching the ..knee. in the cosmic-ray spectrum (supernova remnants arethought to be the main sites of cosmic-ray acceleration). We have analysed theXMM-Newton pointings on SN 1006, and have measured for the first time the radialand azimuthal variations of the synchrotron emission. We propose to finishmapping the whole remnant with deeper exposures, allowing to measure thenon-thermal emission outside the bright limbs (the current constraint is morelike an upper limit).

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.
