【摘要】 基于Labview虚拟仪器技术的反应堆噪声分析测试系统,先由堆内γ补偿电离室探测到中子在堆内的统计涨落中子噪声电流信号。该信号经前置放大器放大后,送入I/V转换模块,再和SCB-68端子板通道相连,由高速同步数据采集卡PCI-6143完成信号的同步采集。最后,把所得的数据输入计算机完成数据分析处理。更多还原

【Abstract】 Reactor noise analysis and testing system based on labview virtual technique. Firstly, using γ-compensation ionization chambers detected the statistic current signal of the neutron fluctuation in reactor. The signal was amplified by the front amplifier, sent to I/V model and then connected with the channels of SCB-68. The high-speed synchronization data acquisition PCI-6143 was used to complete signal data acquisition. Finally, the acquired data weresent to computer and realized the analysis.更多还原
