摘要：

The CDF II detector contains a time-of-flight detector consisting of 216 scintillator bars of 279cm length and 4 x 4 cm(2) cross-section located at a radius of 138 cm from the beam asis. The bars are installed on the inner surface of the CDF solenoid, which produces all axial field of 1.4 T. Nineteen-stage fine-mesh photomultiplier tubes are attached at both ends of the scintillator bars. Photostatistics limit the time-of-flight resolution, which is expected to be 100 ps. The primary physics motivation is K+/- identification for improved neutral B meson flavor determination. (C) 2001 Elsevier Science B.V. All rights reserved.
