用于微中子震荡实验的液体闪烁探测器的探测效率研究(英文)

The study of the detection efficiency of the liquid scintillator for neutrino oscillation experiment

为了台湾微中子震荡实验的设计,研究了正电子的探测效率与触发模型的关系,模拟结果说明,当单元正电子能量阈值为55keV时,以15cn×15 cm单元截面的5×5和7×7单元组成的触发模型的正电子的探测效率可以分别达到60%和70%。它们相关的参数是设计较好的选择。

In order to provide the criteria for the detector and trigger logical design of Taiwan Neutrino Oscillation （TEXNON） experiment, the relationship of the positron detection efficiency with the construction of the detector and the trigger model have been investigate＆ Correspondent results have been obtained, such as the cell size of 15×15 cm^2 , single cell deposited energy threshold set at 55keV,the 5× 5 and 7× 7 cells for triggering gamma ray, the positron detection is about 60% and 70% respectively. This set of parameters is recommended as the better choose of the detector design.
