Simulation study on the timing property of wavelength shifter fiber embedded in a plastic scintillator

The simulation results of the timing properties of a plastic scintillator are reported, when it is read by the WLS fiber. For the sake of completeness, we are beforehand with a simplified formula describing the light propagation in a fiber, and thereafter present the simulation results as the distributions for t₁-t₀ as well as t₁+t₂ to see the time resolution with t₁ and t₂ the times appeared at both fiber ends and t₀ at the trigger source. The simulations were made for two different WLS fibers, Y11 and BCF92, to see the influence of radiation time on the time resolution.
