Forward Time-of-Flight



The Forward Time-of-Flight system will measure the time-of-flight of charged particles emerging from the target. The average distance from the target to the FTOF counters will be approximately 6 m (600 cm).

The FTOF system requires excellent timing resolution for particle identification and good segmentation for flexible triggering and prescaling options.

Layout/Specifications
The design parameters were designed to allow for separation of pions and kaons up to about 3 GeV.

The most energetic particles are formed at smaller angles. The system specifications demand a time resolution of σ=80 ps at the more forward angles of CLAS12 and 150 ps at angles larger than 36 degrees.
