Cross-talk of a multi-anode PMT and attainment of a TOF counter

Abstract We extensively studied a cross-talk phenomenon that seriously deteriorates the high time-resolution of a multi-anode 16-channel linear array photo-multiplier tube (PMT); the dynode structures were modified to eliminate the cross-talk effect and to recover a time resolution of σ = 70 – 80 ps for single photons. The use of 16 anode signals of the modified PMT enabled us to attain σ = 12 ps for a small TOF counter of Cherenkov radiation.
