Abstract

The principles of the layout and operation of data-acquisition electronics for tagged neutron technology are described. They are based on the selection of useful events according to specified criteria with data acquisition by a buffer memory unit and subsequent transfer of data arrays to a remote computer for processing and visualization. The main selection criterion is the presence of signals from the α and γ detectors in specified time intervals and amplitude ranges in the absence of overlapping events. By using a backbone−modular architecture, it is possible to carry out parallel signal processing and data transmission at several levels, which allows connection of almost any number of γ detectors without losing measurement accuracy and data integrity. A model of the setup has been produced for testing the developed equipment, and experiments were conducted to study its characteristics. The experimentally achieved data-transfer rate (for α−γ coincidences) is 3 × 10⁵ s⁻¹, which is several times higher than the maximum transfer rate of existing data-acquisition systems for the tagged neutron technology.

带标记中子的多探头装置数据采集系统与事件并行传输

摘要介绍了用于标记中子技术的数据采集电子装置的布局和运行原理。其基础是根据指定标准选择有用事件，由缓冲存储器单元进行数据采集，然后将数据阵列传输到远程计算机进行处理和可视化。主要的选择标准是在规定的时间间隔和振幅范围内，α 和 γ 探测器发出的信号不存在重叠事件。通过使用主干模块结构，可以在多个层面上进行并行信号处理和数据传输，从而可以连接几乎任意数量的 γ 探测器，而不会降低测量精度和数据完整性。为测试所开发的设备，制作了一个装置模型，并进行了实验来研究其特性。实验达到的数据传输速率（α-γ 重合时）为 3 × 105 s-1，比现有标记中子技术数据采集系统的最大传输速率高出数倍。
