To characterize the time resolution, it was required to quantify the optical photons that reach the <em>Score</em> in a certain time, which are generated by muons on the surface of the plastic scintillator. Different configurations of <em>muon beams</em> were simulated at energy of <em>1 GeV</em>, to interact with the configuration of the scintillator material of its corresponding arrangement. The simulations were made varying three parameters: the scintillator material “<em>BC404 &amp; BC422”, </em>its size, and the location of the radiation source<strong>.</strong> Fifteen simulations correspond to <em>BC404</em> material &amp; fifteen simulations to <em>BC422</em> material respectively. The first five simulations consisted in varying the scintillator’s volumetric size and collocate the <em>muons</em> <em>beam</em> guided <em>randomly distributed</em> over it, the next five simulations differentiate from setting up a <em>directly centered beam</em>, and the last five simulations for guide the <em>beam on the left lower corner</em> of each scintillator.<br>The best time resolution achieved was σ= 8.67 +/− 0.26 ps.<em>,</em> reported by the detector with <em>BC422 </em>scintillator material which has a volume of 20x20x3 mm<sup>3</sup>.</p> ER -
