Timing resolution of the FINUDA scintillation detectors

Experimental characterizations of scintillation detectors timing performance of the internal (TOFINO) and external (TOFONE) scintillator barrels used in FINUDA experiment are presented. asurements take advantage of detecting synchronous particle pairs produced in the reactions, namely e + e - pairs from Bhabha collisions between the primary beams and K + K - pairs from φ (1020) decay. thod used for synchronizing the multiple detectors constituting the scintillator barrels is also described as being carried out in two steps: a rough one online by the injection of laser light pulses flashing the scintillators all together, and a fine one offline exploiting the timing features of e + e - and K + K - pairs.
