Abstract	The 77% of TeV extragalactic sources are BL Lacs. They belong to the Highfrequency peaked BL Lacs (HBLs) subclass characterized by a low-energy componentwith power peaking between the UV and the X-rays. We propose xmm~observations ofa selected sample of HBLs, to study the spectral behavior of their optical toX-ray component. In addition, on the basis of our previous X-ray analyses of TeVe non TeV HBLs, these proposed xmm~observations will allow us to identify BL Laccandidates for future TeV observations.

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.
