Abstract About 20% of Galactic hard X-ray galactic detected in the INTEGRAL and Swiftsurveys are accreting white dwarf binaries (CVs). The majority harbours magneticprimaries, which are disputed to be important contributors to the galacticpopulation of low-luminosity X-ray sources. Optical follow-ups allow to selectgood candidates, but a secure identification resides in the X-rays. XMM-Newtonhas shown the unique potential to detect X-ray spin pulses and caracterize thespectral properties with high S/N data. We here propose 9 new candidates withthe ultimate goal to obtain a flux-limited sample down to 8E-12cgs and allow atrue census of hard X-ray CVs, in view of the accurate distances to be providedshortly by Gaia.

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.
