The new CDFII detector incorporates a Time-of-Flight detector =
(TOF), employing plastic scintillator bars and fine-mesh =
photomultipliers. Since August 2001 the TOF system has been fully =
instrumented and integrated into the CDFII data acquisition system. =
With a design goal of 100 ps resolution the TOF system will provide at =
least two standard deviations separation between K+/- and pi+/- for =
momenta p < 1.6 GeV/c, complementing low momentum particle =
identification by means of the specific ionization energy loss measured =
in the drift chamber. We describe the design of the TOF detector and =
discuss the current status of its calibration and initial performances. =
Finally we review the expected impact of the TOF detector in the flavor =
tagging of neutral B_S meson.
