The forward time-of-flight (TOF) detector is located right in front of the FCAL. It has two planes of scintillator paddles, in one plane the paddles are stacked vertically, in the other horizontally. Each paddle is 252cm long 6cm wide and 2.54cm thick. On both ends the paddles have "fish-tail" type light guides that couple to an XP2020 photo multiplier tube.

=== TOF Detector ===
The pupose of the TOF detector is to provide the means of particle identification (PID) through the measurement of the velocity of the particle passing through the detector volume. This velocity can be determined by measuring the time a particle needs for a given flight distance.
