Large area plastic scintillation detectors are applied widely in modern physics labs due to the development of the time-of-flight technique. They are usually constructed with a module array design, such as the TOF Wall. The performance of such detectors is excellent, but the number of electronics channels is quite large, and the operation and calibration are too complicated. As a result, a large area plastic scintillation detector with only 4 readout signals from the corners is constructed and developed as a simple TOF Wall at ETF in IMP.

Silicon photomultipliers(SiPMs)have obtained a growing attention as an alternative to the traditional photomultiplier tubes in application on the fast detection of scintillation light thanks to their compactness,low cost,low operating voltage,high gain,high photon detection efficiency,excellent resolution for single photon detection,and insensitivity to magnetic fields[1].In considering larger detector sizes,however,the main drawback of the SiPM readout is their small active *** with an active area in the range between 1 and 36 mm2 are now widely ***,the small size of SiPMs can be compensated by using several SiPMs connected in parallel or in series,which is equivalent to a single large SiPM from the circuit *** this report the effect of different connections on the shapes of output signals will be discussed.
