We propose a survey of BL Lacs with XMM/EPIC. The 36 target objects were selected to span the range of continuum shapes in BL Lacs and be the X-ray brightest in every continuum shape class. This program will: (1) define the range of absorption and emission line properties in BL Lacs, and (2) pick out objects deserving of deeper study. This survey will provide the information necessary to place in context RGS observations of individual objects. By probing the X-ray spectrum we will learn information critical to understanding AGN central engines, including absorption edges from high-velocity material in the BLR and possibly interactions between the jet and nuclear medium.

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.
