INTEGRAL has accumlated nearly 2 years of data for the survey of the Galacticplane; coverage has been concentrated on the Galactic centre region and largenumbers of LMXBs have been discovered. The exposure is now steadily building upalong other regions of the Galactic plane. This will inevitably mean that moreHMXBs will become visible so that comparable numbers of these younger systemsmay be investigated. We request XMM observing time to find counterparts for 4unidentified persistent INTEGRAL sources discovered by IBIS/ISGRI, clustered ina region tangential to a spiral arm, and thus are good HMXB candidates. We planto measure their X-ray spectra and position to permit follow up studies in theoptical/IR bands and thus identify the true nature of the underlying system.

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.
