Abstract We propose a study of the angular correlation in the diffuse X-ray backgroundpointing toward a low hydrogen column density, high latitude line of sight nearthe Eridanus x-ray enhancement. The observation will allow an accuratedetermination of the angular autocorrelation function on the scale 0..5-30.which is almost unexplored so far, and which is expected to contain informationon the X-ray emission due to the Warm-Hot Intergalactic Medium. The contributionof the foreground will be removed using a pointing toward MBM20, a nearby highdensity cloud. The shadow of the cloud will also be used to study the energydistribution of the X-ray foreground in the energy range 0.2-2 keV, to separateO-VII, O-VIII and Fe-XVII lines and study the composition and evolution of the local bubble.

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.
