Abstract

A Time-of-Flight detector (TOF), with a technique based on plastic scintillators and finemesh photomultipliers, has been added to the CDF-II experiment. The main physics motivation is to improve neutral B meson flavor determination by K± identification. The expected time resolution is 100 ps, which provides at least two standard deviations separation between K± and π± for momenta p < 1.6 Gev/cand better than 1.2 standard deviations separation over all momenta when combining TOF identification with dE/dx identification using the new drift chamber.
