Abstract	In a survey of the Galactic plane performed in 2007 with the High EnergyStereoscopic System (H.E.S.S.) a lot of new sources have been discovered andmost of them are still unidentified. We propose to use XMM-Newton to performfollow-up on the two brightest newly discovered sources, namely HESS J1507-622and HESS J1843-033, to identify their possible X-ray counterparts. Both sourceshave no clear positional counterparts: HESS J1507-622 does not show anycounterpart at all, whereas an offset PWN is one of the possible explanationsfor HESS J1843-033. The aim is to obtain the morphological and spectralinformation of the possible counterpart in helping to understand the emissionmechanism of these 2 sources: the predicted X-ray flux is sufficient for detailed studies of these sources.

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.
