The spectral components of polars strongly magnetic CVs were barely disentangledby previous X-ray missions. The physics of accretion in a strongly magnetic,non-relativistic environment is therefore still puzzling. XMM-Newton can solvethe riddle, but the frequent low states of the brightest members preventedsystematic studies. We thus began TOO-like XMM-Newton observations of thebrightest systems in their high states. We are in the process creating asynoptic view on the HARPs and propose to continue in AO12 with one furthertrigger. We will investigate the physics of the hard X-ray emitting shock, theheated accretion pole cap, the atmosphere of the white dwarf, the absorption inthe shock and in the flow, the lines in the accretion flow and the reflection from the white dwarf.

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.
