The Vertex Locator (VELO) of the LHCb experiment consists of two halves each equipped with 23 silicon modules along the beam direction. The detector is mounted in a setup similar to Roman pots. The VELO will offer a powerful tool for primary and secondary vertex reconstruction. In order to achieve this, the detector went through a complete and thorough commissioning phase. This process spans a range of activities: individual module characterization in testbeams, detector integration, system tests and offline alignment procedures. After this extensive commissioning period the LHCb experiment entered a new exciting phase during the year 2008. The experiment saw the first beam! Moreover with data taken in the VELO detector the first LHC induced tracks could be reconstructed. © 2009 Elsevier B.V.
