用于ICF实验中超热电子测量的数据采集系统

Data acquisition system based on VXI for ICF

针对超热电子测量中传统的非标采集系统带来的可靠性和集成度低、兼容性差等。缺点,介绍了一套完整的基于波形的数据采集系统,它包括了基于工业标准的VXI总线硬件模块,和在NI公司的集成开发环境LabWindows/CVI下所开发的完整控制软件程序。该数据采集系统可以取代传统的积分谱仪,应用于在激光打靶实验中的超热电子温度测量,还结合实验室测试结果对在不同的触发条件下该系统的性能进行了定量分析。

This paper describes a new data acquisition system for middle speed and low speed signal in ICF experiments, i. e. , the FF detector. It is made up of two parts .. the standard modular hardware based on VXI bus and the flexible software application developed under LabWindows/CVI. This structure takes full advantage of mature industry standard and versatile integrated development environment. It satisfies the request of measuring superthermal electrons in ICF experiments and improves the stability and precision of the old nonstandard acquisition system. In addition, the delay of system under different trigger conditions is carefully measured.
