First tracks produced by the LHC beam during synchronization test, a success (August 2008)

First tracks produced by the LHC beam during synchronization test have been seen in the VELO detector on August 22nd (Friday late afternoon) triggered by the Calorimeter detector SPD saturated by tracks. This was made possible by the perfect monitoring of the LHC beam and very effective communication with the machine. This is a great success for the whole LHCb Collaboration. Congratulations!
