Abstract :
A Time-of-Flight detector (TOF) has been added to the CDF-II experiment to provide charged kaon identification primarily for neutral B meson flavor determination. With its expected 100 ps time-of-flight resolution, the TOF system will be able to provide at least two standard deviation separation between K± and π± for momenta p < 1.6 GeV/c, complementing the specific ionization energy loss, dE/dx, measured in the new drift chamber. This paper describes the TOF detector and reports on the initial performance based on the data collected by the CDF-II so far.
