利用北京谱仪Ⅲ探测器模拟和触发系统模拟程序,研究了北京谱仪Ⅲ电磁量能器的触发方案.根据物理目标设计了中性事例触发,巴巴事例判选和带电事例触发的方案,优化了各触发条件的参数,并仔细研究了对本底的排斥能力.研究了一批典型的物理道,给出了它们的触发效率,同时给出了预期的本底触发事例率.
Using the Beijing spectrometer Ⅲ probe simulation and triggering system simulation program, the triggering scheme of the Beijing spectrometer Ⅲ electromagnetic calorimeter was studied.According to the physical target, the neutral event triggering, Baba case selection and live event triggering were designed and optimized The parameters of each triggering condition are carefully studied, and the ability of repulsion to the background is studied carefully. A series of typical physical paths are studied, their triggering efficiencies are given, and the expected background firing rate is given.
