Scientific paper

We request 3 separate observations of 30ksec each to perform temporal analysis and precision spectroscopy of an intriguing Einstein ring source, PKS 1830-211. Previous X-ray observations of the source have produced conflicting results, and XMM-Newton observations are required to understand this system properly. With the proposed observations we will measure accurately the spectral shape, absorber column density and redshift and variability, if any. This will allow us to determine the properties of the unusual source quasar, the face-on, spiral lensing galaxy which appears to be a damped Lyman alpha absorber, and test the suggestion of microlensing in the host galaxy of the source.
