PSR J1723-28 may represent the second known case (after PSR J1023+0038;Archibald et al. 2009, Science) of a just-formed ..baby. millisecond pulsar.That provides unprecedented possibilities for investigating the last stages ofthe so-called ..recycling process. and the related activation of a millisecondpulsar. In the framework of a large multiwavelength campaign, we request here a55 ks exposure (thus sampling a full orbit of PSR J1723-28) in order to: (i)firmly establishing the X-ray counterpart to the binary; (ii) investigating thenature of the X-ray emission; (iii) constraining the distribution of plasma inthe system and the geometry of the X-ray emission, thanks to the comparision ofthe variability simultaneously observed in the X-ray emission and in the pulsed radio emission.

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.
