Using the SDSS, we have identified a large number of type II quasars(high-luminosity obscured AGN, with L_bol > 10^45 ergs/s) at redshift z < 0.8.We are conducting a comprehensive multi-wavelength follow-up of the mostluminous objects in the sample. We propose to continue our survey of type IIquasars with XMM to obtain a large sample of objects with known X-rayproperties. Our primary goal is to quantify their degree of obscuration. We alsowill study the statistical properties of quantities such as X-ray spectral slopeand L_X/LOIII relative to Seyfert 2 galaxies and for the first time determinethe distribution of the absorbing column densities among the luminous type IIquasars.

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.
