Nab实验将测量自由中子β衰变中的电子-中微子相关性和Fierz干涉项，以检验Standard Model并探索Beyond the Standard Model Physics。使用National Instrument的PXIe-5171可重构示波器模块，我们开发了一种数据获取系统，该系统不仅能够满足Nab的规格要求，而且足够灵活，可根据实验环境的要求进行原位适配。L1和L2触发逻辑可以通过配置文件和LabVIEW控件进行重构，以在运行时优化系统以进行符合事件检测。该系统能够识别至少$1$ MHz的L1触发，同时读出约$2$ GB/s的峰值信号速率。在调试期间，系统以$400$ MB/s的持续读出速率运行，信号数据源自约$6$ kHz的L2触发，完全在系统的峰值性能范围内。
英文摘要：
The Nab experiment will measure the electron-neutrino correlation and Fierz interference term in free neutron beta decay to test the Standard Model and probe Beyond the Standard Model Physics. Using National Instrument's PXIe-5171 Reconfigurable Oscilloscope module, we have developed a data acquisition system that is not only capable of meeting Nab's specifications, but flexible enough to be adapted in situ as the experimental environment dictates. The L1 and L2 trigger logic can be reconfigured to optimize the system for coincidence event detection at runtime through configuration files and LabVIEW controls. This system is capable of identifying L1 triggers at at least $1$ MHz, while reading out a peak signal rate of approximately $2$ GB/s. During commissioning, the system ran at a sustained readout rate of $400$ MB/s of signal data originating from roughly $6$ kHz L2 triggers, well within the peak performance of the system.
