Time Resolution of BC422 Plastic Scintillator Read Out by a SiPM

Plastic scintillators are widely used in particle detectors when precise timing information is required. As a basis for comparing different we use such characteristic as the time resolution per 1MeV detected energy, i.e. expected assuming deposited energy scintillator equals to and all scintillation light collected photosensor. In this work measure parameter with BC422 plastic read out by SiPMs. The best obtained value about 6ps, which almost factor of 3 better compared our earlier result from 2012. Such an improvement represents progress development SiPMs made over these years and, driven progress, improved knowledge know-how on detectors.
