The discovery of SN1006-like SNRs indicates that the SNR shells acceleratecosmic rays up to 100TeV. The number of such SNRs are however still sparse andlimited in our Galaxy. The next step must be made by the discovery of an extra-Galactic SN1006. We propose to observe the best candidate, DEML241 in the LMC.It shows shell-like structure and non-thermal component like SN1006. However,poor spatial resolution and statistics of previous instruments prevent us fromconfirming that DEML241 is an SN1006-like SNR. From the fine spectroscopy andmorphology study of DEML241 with XMM, we must find non-thermal emission from theshell of DEML241 and confirm the SNR as the SN1006 in the LMC, which is a bigstep to start a quantitative study of cosmic ray acceleration.

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.
