We propose to observe two supernova remnants in the Large Magellanic Cloud(LMC), SNR 0534-69.9 and DEM L 316A, thereby completing the sample of known TypeIa remnants in the LMC observed by XMM-Newton. Our goal is to use the X-rayspectra to measure physical conditions in these SNRs. A detailed analysis of theemission from these objects also provides valuable information on their chemicalstructure, which is linked to the explosion mechanism. We will compare theobserved X-ray spectra with spectra calculated from hydrodynamical models. As asample, the LMC Type Ia remnants will allow us to constrain the parameters ofthermonuclear explosion scenarios.

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.
