Abstract The radii of neutron stars are now routinely measured in transient low massX-ray binary systems hosted in globular clusters (GCs). Only a handful of suchsystems are firmly identified, and more are needed to produce a usefully largepopulation. Most -- discovered using Chandra -- are unsuitable for detailedstudy with large area missions, due to the crowded GC fields. We devise a surveystrategy to discover new quiescent transient low-mass-x-ray-binaries (qLMXBs) inGCs suitable for these missions. We expect to detect 2-3 new qLMXBs which can beused for precision NS radius measurements.

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.
