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 t
₁
-t
₀
as well as t
₁
+t
₂
to see the time resolution with t
₁
and t
₂
the times appeared at both fiber ends and t
₀
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.
