This paper studies deeply trigger decision criterion of the PHOS in ALICE experiment by simulation, including three parts: 1) the energy reconstruction performance of PHOS is tested; 2) the selection of trigger threshold is analyzed and the trigger efficiency is calculated; 3) the trigger rate of PHOS is evaluated and its selection is discussed for the different collision mode.
对ALICE实验光子谱仪的触发选判机制进行了模拟研究,内容包括:1)对光子谱仪的能量重建性能进行了研究,通过计算机模拟检验光子谱仪探测器对大横动量范围的入射粒子的能量重建性能; 2)对光子谱仪探测器的事件触发效率进行了研究,通过计算机模拟分析触发阈值的选取并计算触发效率;3)对光子谱仪探测器的事件触发频率进行了研究,通过计算机模拟对p-p和Pb-Pb两种碰撞模式下的触发频率分别进行了估算和讨论。
