Alignment procedure of the LHCb Vertex Detector

Understand

LHCb is one of the four main experiments of the Large Hadron Collider (LHC) project, which will start at CERN in 2008.

• The experiment is primarily dedicated to B-Physics and hence requires precise vertex reconstruction.
• The silicon vertex locator (VELO) has a single hit precision of better than 10 micron and is used both off-line and in the trigger.
• These requirements place strict constraints on its alignment.
