| Abstract | The TeV instrument H.E.S.S. discovered during a survey of the Galactic planethree sources close to highly energetic pulsars. It was hence suggested thatthese gamma-ray sources are counterparts of pulsar wind nebulae (PWN). Indeed,in one of these cases the PWN has been well studied with XMM-Newton, whichallowed a firm identification of the TeV source with the PWN. With thisproposal, we want to use XMM-Newton to identify the X-ray counterpart of HESSJ1804-216. This TeV source can also most likely be explained as emission from aPWN, but so far this PWN around PSR B1800-21 has not been detected in any otherwaveband. The PWN detection may also hold the clue for the so far not firmlyestablished association of PSR B1800-21 to the supernova remnant G8.7-0.1. |

| 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. |
