Abstract We propose to observe the X-ray bright blazar PKS 2155-304 for a full XMM orbitin order to study its time variability with unprecedented time/energyresolution. Long ASCA and SAX observations suggest that soft X-ray photonslag the harder ones by 4 to 0.5 hours. The unique capabilities of XMM will allowto unambiguously confirm these lags and measure their energy dependence withinthe X-ray band and in the UV. The length is dictated by the need to measureshort X-ray lags with high precision as well as long lags expected in the UVArrangements to combine the observations with GTO time are in progress. The data will allow to set new constraints on the mechanisms of particle acceleration and cooling in jets.

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.
