在宇宙射线μ子成像系统中,触发逻辑电路是触发判选系统的重要组成部分,其作用是快速实时的对有效μ子事例进行选择,并产生触发逻辑信号。从漂移管阳极丝输出的信号进入前置放大和主放大器,随后送入定时电路,经定时甄别电路定时以及剔除幅度较小的噪声信号,转换成LVDS差分信号,经长距离传输最终送入时间数字转换器 In the cosmic ray muon imaging system, the trigger logic circuit is an important part of the triggering decision system. Its function is to select valid muon cases in real time and generate trigger logic signals. The signal output from the anode of the drift tube enters the preamplifier and the main amplifier and is then fed into the timing circuit. The timing circuit is timed and the noise signal of a smaller amplitude is removed to convert it into an LVDS differential signal. The long feed-in time Digitizer
