Abstract	We will obtain fluxes and spectra for 5 new magnetic cataclysmic variables(Polars) identified from the first year of the Sloan Digital Sky Survey. Theseobjects are unusual in that they appear to represent the low end of masstransfer in magnetics and have low X-ray/optical fluxes compared to X-rayselected Polars. We will use the high sensitivity and large energy coverage ofXMM to delineate the shock versus blob heating in this low accretion situationas compared to the high accretion states that are usual in X-ray selectedmagnetics. These results will test the available accretion models in highmagnetic field regimes.

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.
