A Time-of-Flight detector (TOF) has been incorporated into the CDF-II exper
iment in order to provide charged kaon identification to improve neutral B
meson flavor determination. With an expected time-of-flight resolution of 1
00 ps, the system will be able to provide 2 standard deviation separation b
etween K+/- and pi (+/-) for momenta p < 1.6 GeV/c, complementing the speci
fic ionization energy loss dE/dx measured with the new drift chamber.
