Abstract :
We developed a timing counter with a monolithic array of multi-pixel photon counters (MPPCs) coupled to a 10 ×12.6 ×24 mm3 plastic scintillator. A signal of the MPPC was processed and its fast components were amplified by a developed readout circuit to improve the timing. The performances of the counter were evaluated by electrons with energies of 855 MeV. A set of the MPPC based scintillation counter and a PMT based reference counter achieved the TOF resolution less than 80 ps ( σ). The gain was almost constant up to the count rate of 170 kHz.
