介绍了一个可广泛适用于数据获取系统中用作事件触发发生器的 NIM插件 ,它对具有众多相关参数的多举物理实验的实验数据进行有效逻辑处理及筛选。它根据预置的符合重数“N”的大小 ,输出一个 NIM信号“OUT”去触发数据获取系统和 ADC(或 TDC) ,对产生≥ N重符合的事件的实验信号进行数据转换 ,而忽略小于 N重符合的事件 ,从而得到符合事件的多重性及其分布。并使得后台数据获取系统的计算机能更容易和快速地对实验数据进行筛选和获取 ,去除掉大量无用数据 ,筛选掉大量低符合重数的事件 ,提高了实验的效率 ,节省了束流时间。 A NIM plug-in that can be widely used in data acquisition systems as an event trigger generator is introduced. It effectively processes and filters experimental data of multiple physical experiments with many related parameters. It outputs a NIM signal “OUT” to trigger the data acquisition system and the ADC (or TDC) according to the preset size matching the weight “N” to convert the experimental signal that generates ≧ N coincident events and ignore Less than N coincident events, which are consistent with the event’s multiplicity and its distribution. And makes the computer of the background data acquisition system more easily and rapidly filter and acquire the experimental data, remove a great deal of useless data, filter out a large number of events that are less than the heavy number, improve the experiment efficiency and save the beaming time.
