A Time-of-Flight (TOF) detector, based on plastic scintillator
and fine-mesh photomultiplier tubes, has been added to the CDF-II
experiment. Since August 2001, the TOF system has been fully instrumented
and integrated into the CDF-II data acquisition system. The TOF system will
provide particle identification of low momentum charged pions, kaons and
protons in p anti-p collisions. With a design resolution goal of about 100 ps,
separation between charged kaons and pions is expected at the 2 sigma level
for momenta below 1.6 GeV/c, which enhances CDF's b-flavor tagging
capabilities. We describe the design of the TOF detector and discuss its
on-line and off-line calibration. Some performance benchmarks using
proton-antiproton collision data are presented.
