On behalf of the ATLAS Upgrade Workshop Organizing Committee, the Local Organizing Committee at IFIC-Valencia invites you to the ATLAS Tracker Upgrade Workshop 2007. It will be held at Valencia, Spain, from Wednesday December 12th through Friday December 14th.

The Valencia ATLAS Tracker Upgrade Workshop is next in a continuing series of workshops (Genova 2005, Liverpool 2006) on the ATLAS detector issues of a future high luminosity upgrade of the LHC.

The Valencia meeting will review and make progress toward the engineering conceptual layout. It will also cover reports from the different working groups.
