In this paper , the time property of its anode and dynode outputs has been studied and compared by using weak cherenkov light , the results show that their time resolution is dependent on the number of the electrons collected at the same conditions 為了獲得多個倍增極的輸出信號,對其進行了相應的改進,利用弱契倫科夫光,研究了其陽極和倍增極的時間特性,并作了比較,結果表明相同條件下它們的時間分辨與所收集的電子數有很大關系。
