Particle ID for τcF via TOF

3σK-π separation at 1 GeV/c via time-of-flight (TOF) scintillation counters in the anticipated τcF geometry requires ∼ 120 ps time resolution. A prototype counter using a bundle of scintillating fibers 6.15 m long and 5 cm x 5 cm in cross section has been studied. The arrival time of cosmic rays passing 3 m from a photomultiplier has been measured with an observed resolution σ=237 ps thus indicating that two layers of counters each looked at by photomultipliers at both ends can provide the needed time resolution. A new particle ID technique called Cerenkov Correlated Timing which may be important for a τcF is briefly described. (author). 4 refs., 17 figs., 2 tabs
