New optically identified Cataclysmic Variables (CVs) have recently increased ascandidates the number of Intermediate Polar systems making them nowdays aconspicuous and important class for the study of the evolution of magnetic CVs.Among 15 candidates representing about 50% of the class, we propose to observefive new systems recently found to be strong optical pulsators. The detection ofX-ray pulses at the white dwarf spin period and their spectral properties willprovide firm constraints on their true magnetic nature thus helping inreconciling the still fragmentary picture of accretion and evolution of magneticCVs.

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.
