Operational experience with the CDF run II silicon detector

CDF (collider detector at Fermilab) silicon vertex detector consists of three subdetectors: SVX-II, ISL and L00. Altogether it consists of 8 layers of silicon with more than 720,000 readout channels. This detector is essential for CDF´s high precision tracking. It is also vital for the forward tracking capabilities and the identification of heavy flavour decays. After four years of data taking in run-II and a delivered luminosity of more than 1.2 fb^-1, a summary of the operational experiences with a silicon detector at CDF is given. Besides being very important for the tracking, the silicon detector also plays a vital role in level 2 decision of the CDF trigger system. Finally, aspects of the longevity of this detector and the impact on the CDF physics programme are presented
