采用LabVIEW开发平台,用虚拟仪器技术进行了γ能谱仪的设计和开发。简述了γ能谱仪硬件组成、参数要求、软件设计原理及功能。采用高速数据采集卡,使数据采集速度远大于LabVIEW开发软件的读取速度。系统中嵌入运行速度很快的采集控件,成功地解决了仪器读写速度匹配问题,提高了仪器的性能。
A gamma-ray spectrometer was developed based on LabVIEW programming technique. The hardware configuration, parameter requirements, software design and performance of the γ spectrometer were described. With a high-speed data-collection card, its data collection was much faster than reading speed of the LabVIEW software. In order to solve the access rate-matching problem, a collecting component with very high operation speed was used. This improves the system's performance.
