Abstract	Vela X is a bright nearby composite SNR in which interactions of the reverseshock with the central pulsar wind nebula have produced a complex emissionstructure. Broadband modeling indicates a spectral disconnect between thepopulations of radio and X-ray emitting particles, and subsequent gamma-raymeasurements appear to confirm this. In particular, recent measurements with theFermi LAT reveal that the peak of the GeV gamma-ray emission is spatiallyseparated from the dominant regions of emission in hard X-rays and TeVgamma-rays. We propose an XMM observation of the GeV emission peak region toprovide spectra for comparison of the nonthermal X-ray emission with that fromother regions within the PWN.

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.
