Among hard X-ray galactic sources detected by the INTEGRAL and Swift surveysthose identified as white dwarf binaries (CVs) recently boosted in number. Themajority harbour asynchronously rotating magnetic primaries, suggesting thatthis subclass could be an important constituent of X-ray binary populations.XMM-Newton demonstrated its unique potential to unambiguously infer their truenature through the detection of X-ray spin pulses and the study of broad-bandspectra, that proved to be successful for more than 17 targets. We propose tocontinue our identification programme with the ultimate goal to obtain a truecensus of the first volume-limited sample of hard X-ray emitting white dwarfsystems.

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.
