Abstract	GT- EX Hya is an eclipsing intermediate polar-type CV with an orbital period of98 min and a white dwarf spin period of 67 min. The sources spectacular ASCAspectrum has been analyzed and interpreted by Fujimoto & Ishida (1997) andAllan, Hellier, and Beardmore (1997) with differing conclusions about theelemental abundances and the applicability of the Aizu model of the accretioncolumn. We propose to utilize the large area, wide bandpass, and high spectralresolution of XMM to resolve these discrepancies. With the RGS spectrum we willfor example strongly constrain the density of the plasma from the line ratiosof Fe L-shell transitions and the low-temperature end of the DEM distributionfrom the K alpha emission line ratios of H- and He-like O, Ne, Mg, and Si.

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.
