GT-The magnetic CV RX J1940.1-1025 belongs to the small group ofpolars with a slight non-synchronism between the WD spin and the binary period. With an XMM observation of 25 ks two complete binaryorbits can be covered without data gaps. The spectral analysis willsimultaneously cover the soft BB component and the hard Thermal Bremsstrahlung component. The timing analysis will cover the timedependent absorption (.troughs. and .dips.) by the accretion flowand probe the physics and geometry of the structured inhomogeneousaccretion stream.

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.
