We request a 40-ks XMM pulse-phase spectroscopic observation of theremarkable, possibly ultra-magnetized X-ray pulsar, 1E 1841-045. Thepulsar is associated with the young (virgul2,000 yr-old) SNR Kes 73. Itsslow, 12-s rotation is unprecedented for its youth, raising theintriguing possibility that the pulsar possesses an enormous surfacemagnetic field of nearly B virgul1015 G, a 1000X stronger than for atypical radio pulsar. The proposed observation will yield an unprecedentedspectral measurement - providing a phased stellar spectrum explore the nature ofthe emissions. These observations will help advance our understanding of youngneutrons stars, in particular the magnetar phenomena.

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.
