Performance of the ZEUS Micro-Vertex Detector

The ZEUS Micro-Vertex Detector (MVD) was installed in 2001 and the ZEUS experiment has started the HERA-II data taking since 2003. An integrated luminosity of 190 pb - 1 has been recorded at HERA-II which already exceeds the total integrated luminosity at HERA-I. The operational experience with the MVD and the performance of the new ZEUS tracking system are presented.
