Abstract	We will perform EPIC observations of two Galactic globular clusters to detectthe cataclysmic variables (and other binaries or their progeny) in theseclusters. From the spectra (or X-ray colours) and lightcurves we will determinethe nature of the X-ray sources, identify the cataclysmic variable orbitalperiods and detect white dwarf spin periods in the brightest intermediate polars(magnetic cataclysmic variables), to show why cataclysmic variables show feweroutbursts in globular clusters than in the field. The populations, positions andnature of the objects will also help us understand the formation mechanism ofcataclysmic variables in globular clusters and to comprehend their possiblecontribution in slowing the inevitable core collapse of these very dense stellar systems.

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.
