一、引言FH4-022相加器是常用核电子学仪器的一种,该仪器可用来将四路,三路或二路的信号线性相加。如在用探测望远镜识别粒子时,可将E,△E信号相加求得全能粒子,或在水中氚的连续监测装置中把工作于同一闪烁晶体的多个光电倍加管输出相加,以提高信噪比等。本仪器也可将电子系统中各监测点作为信号输入,在不中断系统工作的情况下,将各监测点信号送到监测设备处理而达到监测的目的。
I. INTRODUCTION The FH4-022 adder is a type of commonly used nuclear electronics instrument that can be used to linearly add four, three or two signals. Such as the use of detection telescopes to identify particles, E, △ E signal can be summed to obtain all-round particles, or tritium in water continuous monitoring device to work in the same scintillation crystal multiple photomultiplier tube output added to increase Signal to noise ratio and so on. The instrument can also be the electronic system monitoring points as a signal input, without interrupting the work of the system, the monitoring point signal sent to the monitoring equipment to achieve the purpose of monitoring.
