We propose 3 brief EPIC observations of regions of the evolved shell-like SNRG182.4+4.3. This SNR has attributes similar to those of an emerging subclass ofSNRs. These other remnants, RX J1713.3-3946, RX J0852.0-4622, and SN1006, allhave low X-ray and radio surface brightness with strong morphological overlap.All are expanding into very low density media. Their X-ray emission is dominatedby synchrotron radiation from shock accelerated electrons, and they thus serveas laboratories for cosmic ray acceleration studies. SNR G182.4+4.3, stillundetected in X-rays, is older than these others and therefore allows study ofthe evolution of shock acceleration in SNRs. EPIC observations allow us to mapthe X-ray emission and determine spectrally the mechanism(s) responsible.

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.
