为了完成多参量关联实验,国外普遍使用具有多个ADC输入端的计算机多维多道。 根据多参量实验测量的事件率通常十分低,占空比一般只有百分之几的特点,我们建立了一个由少量电子学插件组成的四参量数据获取系统。通过选择开关可以对两参量、三参量以及四参量关联实验数据进行自动获取,数据以数字打印的形式输出。
In order to complete the multi-parameter correlation experiment, a multi-dimensional multi-channel computer with multiple ADC inputs is generally used abroad. According to the multi-parameter experimental measurement of the event rate is usually very low, the duty cycle is generally only a few percent, we have built a small amount of electronic components of the four-parameter data acquisition system. The two-parameter, three-parameter and four-parameter related experimental data can be automatically acquired by selecting the switch, and the data is output in the form of digital printing.
