SNR G22.7-0.2 is a well-resolved shell (26. in diameter), observed in a largemulti-wavelength dataset. It is possibly in interaction with the adjacent SNRG23.3-0.3, with likely consequences for high-energy particle production. Thesecircumstances make this SNR a good candidate for a detailed study in the keVband, which is still missing. We propose a full coverage of the SNR shell withemph{XMM-Newton}, to complete the characterization of its parameters, startingwith its age and distance, as well as to map the properties of non-thermalparticles around its shell and study the proposed SNR-SNR interaction region.

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.
