The detector was simulated based on Monte Carlo, including its geometry, energy deposition, photon collection and signal generation. The detection efficiency and the real events selection have been obtained while the background noise has been reduced by using two-end readout timing window coincidence. We developed an off-line analysis code, which is suitable for massive data from the digitizer. We set different coincidence timing windows, and did the off-line data processing respectively. We find the detection efficiency increases as the width of the timing window increases, and when the width of timing window is more than 10ns, the detection efficiency will slowly grow until it reaches saturation. Time, position and energy response have been measured by exposing to radioactive sources. The best timing window parameter as 16ns is obtained for on-line coincidence measurement, and the position resolution is up to 12cm. Energy response of the detector was linear within the experimental energy range*.
