Abstract

A Time-of-Flight detector (TOF) has been added to the CDF-II experiment to provide charged kaon identification primarily for neutral B meson flavor determination. The TOF front end electronics system has 432 channels and is designed to run at the 7.58 MHz bunch crossing rate in CDF. The electronics contributes less than 25 ps to the anticipated TOF timing resolution of 100 ps, which is dominated by photon statistics. This paper describes the design and implementation of the electronics as well as the initial in situ performance.
