The global structure of the the multiphase interstellar medium (ISM),and particularly the proportion of hot gas within it, is largelydependent upon the contributions of energy and hot gas fromsupernova remnants (SNRs). To examine the amount of hot gas transferred from SNRs to the ISM, it is necessary to examine the cooling of this gas in the cavities of evolved SNRs. We therefore propose observations of three SNRs -- N 206, SNR 0450-709, and N120 -- which are among the oldest in the Large Magellanic Cloud (LMC), and therefore allow us to study evolved SNRs without Galactic

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.
